###### Keynote: Group theory, coherent states, and the N-dimensional oscillator

Time : **09:30-10:05**

##### Biography:

Carl R Hagen received PhD from the Massachusetts Institute of Technology in 1962. He has been with the University of Rochester since 1965 and was named Professor in 1974. He is a fellow of the American Physical Society. He was named an Outstanding Referee by the American Physical Society in 2008 and was awarded the Society's 2010 J. J. Sakurai Prize in theoretical particle physics for "elucidation of the properties of spontaneous symmetry breaking in four-dimensional relativistic gauge theory and of the mechanism for the consistent generation of vector boson masses."

##### Abstract:

The isotropic harmonic oscillator in N dimensions is shown to have an underlying symmetry group O(2,1) x O(N) which implies a unique result for the energy spectrum of the system. Raising and lowering operators analogous to those of the one-dimensional oscillator are given for each value of the angular momentum parameter. This allows the construction of an infinite number of coherent states to be carried out. In the N=1 case there is a twofold family of coherent states, a particular linear combination of which coincides with the single set already well known for that case. Wave functions are readily derived which require only the solution of a first order differential equation, an attribute generally characteristic of group theoretical approaches.

##### Abstract:

Gamma ray bursts (GRB) are ultra-luminous events occurring throught the universe, which flood an almost dark gamma-ray sky for a short period of time, a few to several hundred seconds. The currently accepted interpretation of this phenomenon is that a few solar rest mass worth of gravitational energy is released in a very short period in very small regions in an enormous explosion. It is caused by either the merger of two compact objects or collapse of a massive star. I will review the latter case, generally known as a collapser model of GRB, in my presentation.

##### Abstract:

It is well documented that electrons and all particles (even as heavy as fullerenes) produce the same interference patterns as photons in the two-slit experiment. Nevertheless, the description of these patterns remained markedly different thus far. The difference was studied in detail by David Bohm. Recently, Sanz and Miret-Artes were able to squeeze it to zero. Fortunately, they left some room for further improvements. They are going to be presented in the talk. In it, we observe that in the absence of sources the electromagnetic field can be described without loss of generality in terms of the complex scalar field. Previously, the electromagnetic field was described either with help of the massless Dirac-type fields or via complicated matrix (Duffin-Kemmer) Dirac-like formalism developed by Harish-Chandra. As noticed by Freeman Dyson, such a formalism is useful for description of meson-nucleon interactions in Yukawa-style calculations. Use of new complex field not only simplifies these and other calculations considerably but also allows us to demonstrate field-theoretically its equivalence with the complex scalar field entering the non-relativistic Schrödinger equation. Such a coincidence is not fully unexpected in view of the fact that both the electromagnetic (Maxwell) and the Schrödinger equations are invariant with respect to the action of conformal group O (2, 4). Upon development based on ideas by Nambu, this observation is used for development of the Regge mass spectrum formalism for hadrons.

##### Abstract:

An anomaly strong radial magnetic field near the galactic center (GC) is detected. The lower limit of the radial magnetic field at r=0.12 pc from the GC is . Its possible scientific significances are following: The black hole model at the GC is incorrect. The reason is very simple as follows. the radiations observed from the region neighbor of the GC are hardly emitted by the gas of accretion disk which is prevented from approaching to the GC by the abnormally strong radial magnetic field. This is an anticipated signal for existence of magnetic monopoles (MM). The lower limit of the detected radial magnetic field is quantitatively in agreement with the prediction of the paper “An AGN model with MM”. Magnetic monopoles may play a key role in some very important astrophysical problems: Nucleons may decay catalyzed by MM (RC effect according to the particle physics). Taking the RC effect as an energy source, we have proposed an unified model for various supernova explosion. And we may explain the physical reason of the Hot Big Bang of the Universe with the similar mechanism of supernova explosion by using the RC effect as an energy source.

##### Abstract:

The compact and, with 4.3+-0.3 million solar masses, very massive object located at the center of the Milky Way is currently the very best candidate for a supermassive black hole (SMBH) in our immediate vicinity. The strongest evidence for this is provided by measurements of stellar orbits, variable X-ray emission, and strongly variable polarized near-infrared emission from the location of the radio source Sagittarius~A* (SgrA*) in the middle of the central stellar cluster. If SgrA* is indeed a SMBH it will, in projection onto the sky, have the largest event horizon and will certainly be the first and most important target of the event horizon telescope (EHT) very long baseline interferometry (VLBI) observations currently being prepared. It is, however, unclear when the ever mounting evidence for SgrA* being associated with a SMBH will suffice as a convincing proof. Additional compelling evidence may come from future gravitational wave observatories. We treat theory and observations in the framework of the philosophical discussions about (Anti)Realism and Under- determination, as this line of arguments allows us to describe the situation in observational astrophysics with respect to supermassive black holes. Questions concerning the existence of supermassive black holes and in particular SgrA* are discussed using causation as an indispensable element. We show that the results of our investigation are convincingly mapped out by this combination of concepts.

###### Title: Electromagnetic component of physical vacuum as a basic energy containing medium the ether of the universe: Phenomenology

##### Biography:

Serge F Timashev is Professor of Physics in Russian University of Friendship, Moscow. He is also a senior researcher in USPolyResearch, USA. And he is the Head of Laboratory of Membrane Processes. Karpov Institute of Physical Chemistry, Moscow.

##### Abstract:

Today we can talk about a crisis of the modern astrophysics. The magnitude of the cosmological constant , which in accordance with Einstein’s equations of general relativity (GTR) is determined by the energy density of the physical vacuum, exceeds the experimentally determined value by 120 orders of magnitude if one uses the accepted ideas about the big bang dynamics for calculation. In the talk will be shown that the physical essence of emerging problems should first be understood at the level of the transcendental phenomenology. The ground for creating the corresponding phenomenological construction is an introduction into the physical science of a basic energy-containing medium, a sort of an ether, which is identified with the electromagnetic component of the physical vacuum – EM vacuum and which is considered as the basic reference system, tied to the expanding Universe. It is believed that the universe is an open system and the source of energy that feeds the universe is the external false vacuum, which is more energy-intensive than the EM vacuum of our Universe. It is assumed that the energetic power that constantly feeds our universe across the boundary the false vacuum – EM vacuum is equal to the Planck power. In this case, the energy flow entering the universe determines, after the Hubble equation is taken into account, the equation for the dynamics of the universe expansion (an analog of the first Friedmann equation), and the rate of the Universe volume increase determines the operating pressure. It is shown that the energy density of the EM vacuum calculated on the basis of such representations is in full correspondence with the magnitude (the solution of the 120 orders problem). In accordance with the general Casimir idea, all elementary particles and atomic nuclei in the Universe are open to the EM vacuum, and the Casimir polarization of the EM vacuum in the vicinity of each elementary particle or atomic nucleus is formed. It is shown that it is within the framework of such representations the essence of the gravity phenomenon and the origin of the unique smallness of the gravitational interaction in comparison with the nuclear (strong and weak) and electromagnetic interaction can be understood. It can be assumed that it is the wave propagation of the EM vacuum perturbation was recorded in the recent LIGO observation, and this disturbance could arise in the collision of two neutron stars or by some other large-scale events.

###### Title: The energy loss of relativistic heavy ions in a gadolinium foil below and above the ferromagnetic Curie temperature

##### Biography:

We report on high-precision measurements (relative accuracy 3 10^{-5}) with the high-resolving mass spectrometer FRS at GSI. Bi ions with an energy of 52 GeV traversed a polycrystalline Gd foil of a thickness of 1.2 mm placed in an external magnetic field of 450 Gauss. The energy loss of these ions after passage the foil was measured as a function of the foil temperature T below and above the ferromagnetic Curie temperature T_{C} of about 19 ℃. Further, the macroscopic magnetization M of the used Gd foil was measured as a function of the foil temperature T. The data showed the well-known drop of M approaching T_{C} from lower temperatures. Due to an applied external magnetic field, M does not disappear at T_{C} but exists up-to much higher temperatures reaching 90 ℃. Subtraction of effects due to the thermal expansion and due to a measured asymmetric change of the appearing charge-state distribution of the Bi ions when traversing the Gd foil, the remaining relative energy-loss change (δE/dE)_{corr} increased between 5 ℃ and 98 ℃ from 0 to 1.1(5) 10-3. Between 13 ℃ and 15 ℃ a sharp increase of 0.26(3) 10-3 was observed. A presentation of (δE/dE)_{corr} as a function of the negative logarithm of M, namely –ln M, showed an interesting regular step-wise behavior.

##### Abstract:

The quantum Hall effect as observed in semiconductor devices is one of the most interesting and outstanding experimental realizations of the so called Ө vacuum concept in quantum field theory. In this talk, I will review some of the major advances and persistent mistakes that have spanned the subject for more than three decades. I will show how the physics of the quantum Hall effect sheds new light on the notorious strong coupling problems in theoretical physics.This includes the concept of integral topological charge and the conflicting ideas pursued by different schools of thought, in particular, the instanton picture of the Ө vacuum and the large N picture. As a second novel feature I will address the topological classification of field configurations in the bulk and edge modes. This classification has major consequences for quantum field theory where the existence of massless chiral edge excitations was historically unrecognized. I will discuss how the concept of super universality emerges from the existence of these critical edge modes. In dramatic contrast to the historical expectations, super universality tells us that the basic feautures of the quantum Hall effect (i.e. robust quantization, quantum criticality of the plateau transitions etc.) are all intrinsic topological features of the Ө vacuum which are independent of the mathematical details (such as the number of field components or replica method) as well as physical details of the theory (such as the presence or absence of interaction effects). In the last part of this talk I will present the recent advances made on super universality in dimerised SU(N) quantum spin chains. This includes the Haldane mapping onto the sigma model and the numerical simulations that demonstrate the basic principlles of super universality.

##### Abstract:

Since a decade the cube kilometer IceCube neutrino detector did collect several hundreds of thousands of neutrinos events spread over the sky, at TeVs energies, all the atmospheric nature, mainly dominated by muon track component. However, in the last four years the sudden rise above 60 TeV up PeV energy neutrino of 54 events, whose main signature (cascade showers) became suggestive of the injection by a new, expected, ruling astrophysical component. Indeed, the GRB average power fluence is comparable with the observed new neutrino cascade signals. But no GRB among a thousand was found correlated with those neutrino tracks or cascades. Nor blazing AGN or BL Lac correlated with these new astrophysical highest energy neutrino events. Moreover, there is a dozen of neutrino events above 200 TeV whose flavor is not yet showering as a tau flavor, even it could be observed by its double bang. Finally, at 6.3 PeV energy, a Glashow resonance might rise by antineutrino electron scattering on electrons. This resonance, greatly enhanced respect more common neutrino-nucleon interaction, is absent. Either a sudden cut off should occur or some puzzle is wondering. These chains of missing observations stand in favor of a radical solution: most (at least two thirds) of the observed signals are just prompt charmed atmospheric neutrino; maybe only a minor component of an astrophysical nature might be a part of these highest energy IceCube neutrinos. The tau appearance is a key prove (and its absence, a disclaimer) of any neutrino astronomy.

##### Abstract:

Starting with a not very much known relation between the Lorentz group and the Lorentz Force in plain words, between the geometry of Minkowskian spacetime and electromagnetic forces, we generalize this idea to Weyl 2-spinor space and obtain a coupled linear spinor first order differential equations equivalent to the Lorentz Force. We discuss some solutions which have no counterpart within the tensor formalism describing intrinsic spin ½, it is known that every tensor equation can be written in 2-spinor form while the opposite assertion is not necessarily true. Next, a Lagrangian density having units of energy per unit length defined along the classical path of the particle and a U (1) local gauge symmetry with a field coupling in terms of the field strength quantities (instead of the usual four potentials) is proposed. Next, we extend the former description to SU (3) non-abelian symmetry and obtain classical spinor equations describing the dynamics, in the classical, high energy limit, of quark-quark (or antiquark) interactions mediated by gluonic color forces. From the eight gluon fields associated with SU (3), it is shown that two of them (colorless but not in a single combination) give rise to the same kind of interaction described by electrodynamics. We end the presentation, with an informal discussion about an eventual reformulation of the standard model in the 2-spinor language having, as a classical limit, the spinor equations that have been previously considered.

###### Title: Finite-temperature effective potentials in models with extended Higgs sector

##### Biography:

##### Abstract:

In this report authors discuss features of some topological methods for baryogenesis and phase transition, including models with an extended NMSSM scalar sector at finite temperatures. The classic picture of baryogenesis in grand unification theories has changed significantly with the specification and standard model development and the phase diagram of electroweak interactions with experimental data on Higgs boson physics. Currently (especially after the discovery of a particle candidate for Higgs boson role) the minimal extension of the scalar sector has a less likely to be realized, therefore, an important role is played by researching of the non-minimal extensions. In previous papers authors considered a general scalar Higgs sector, including the violation of CP-invariance and temperature corrections for control parameters. Conditions for effective potential of the model NMSSM that lead to the phase transition of the first order strong required for the generation of the observed baryon asymmetry. Additional chiral field plays here the role of the phase transition stabilizing foam. The feature of the upcoming research is that the violations of symmetries and temperature contributions of the self-potential affect the dark sector is supersymmetric models, which could have consequences for cosmology. That is to significantly change the mass of the cold dark matter particles and intensity of their interaction with other particles and the ability to participate in electroweak decays, including the decay of Higgs bosons. Results for Higgs fields in the case of CP-violating and temperature corrections are used for dark sector physical parameters calculations. Also, the annihilation of neutralinos in the framework of quantum field theory in conjunction with Feynman diagram approach was taking into account with one-loop corrections. Temperature one-loop effective potential for NMSSM is reconstructed, including self-energy corrections (i.e., corrections to the mass parameters of dimension 2 of the Higgs potential). Physical mass condition is determined and the one-loop corrections to the dimensionless parameters of the effective potential are evaluated in the framework of non-minimal supersymmetric model (NMSSM). General case is investigated for calculations of one-loop diagrams with different masses in finite temperature field theory, some representations of infinite series and generalized function of Hurwitz are proposed. Surfaces of the stationary points in space background fields and matrix stability are reconstructed, including difference from SM physical basis in alignment limit. The first and second differential forms are implemented for the effective potential. Scenarios of stationary points are in determination, extreme curves and surfaces based on the definition of Grobner bases will be also considered later.

###### Title: Microfocus Bremsstrahlung Source Based on Betatron High-Resolution Radiography and Tomography

##### Biography:

V A Smolyanskiy received his Master’s degree from Tomsk Polytechnic University (TPU). At present, I am a post-graduate student in TPU. I study under the program «Photonics, Instrument Making, Optical and Bioengineering Systems and Technologies», specialty «Instruments and Methods of Control over Environment, Substances, Materials and Products». I also work in the research and production laboratory "Betatron tomography of large-sized objects". My research is devoted to innovative and highly effective methods for generating hard bremsstrahlung with a photon energy of more than 1 MeV for use in high-resolution tomography.

##### Abstract:

The production of a microfocus radiation source based on relativistic electron beams is important for high resolution radiography and tomography. Ordinary betatrons generating secondary hard radiation caused by interaction of the internal electron beam with the target (typically a thick target), that is larger in its area than the cross section of the millimeter-size beam, are used for obtaining the images of a number of objects. But, in [1, 2] the idea was proposed to use internal target much smaller than diameter of the electron beam of the cyclic accelerator to reduce the focal spot of the generated Bremstrahlung. Here, if the beam will circulate for a sufficiently long time on the radius of the micro-target location, then, due to betatron oscillations, electrons will fall on such a target with a sufficiently high efficiency. This paper presents the results obtained for generation of linear-microfocus Bremsstrahlung under interaction of 18 MeV electrons with thin target which was oriented along the direction of the internal beam of the B–18 betatron in order that the electrons can interact with the narrow front face of the target. Magnified images of the compound steel object have been obtained using the radiations generated in the narrow internal Ta targets, the width of which is approximately 100 times smaller than the diameter of the electron beam. The formation of the object structure image with participation of the absorption and phase contrast effects is shown. The study has shown the possibility to successfully generate hard radiation in a narrow target which width is about one hundred times smaller than the diameter of the betatron electron beam, and to use this radiation for obtaining the magnified high-resolution images of micro-defects into products made of heavy materials with participation both the absorption and phase contrast effects in formation of the images. In our case, the radiation spectrum of the betatron generated in narrow internal targets extends from several keV to 18 MeV. For light targets, the images of non-thick objects are formed by a soft part of the radiation spectrum. In our case of heavy target, the radiation spectrum is dominated by hard radiation due to strong absorption of radiation of the soft part of the bremsstrahlung spectrum in the target. The radiation generated in such target is applicable for obtaining images of thick objects made from heavy materials. The images of a compound object consisted of four steel bars demonstrated the high resolution of a series of 10 μm gaps between adjacent bars due to the small horizontal size of the focal spot of the linear microfocus bremsstrahlung source. The results also demonstrate the edge phase contrast due to the high degree of spatial coherence of the radiation. The obtained results attest to the high quality of the radiation beam generated by new microfocus source based on compact betatron that can also be used in a laboratory physical experiment, for example, in materials science to study internal interfaces of media, microdefects and micro-inclusions in the heavy composite materials. In our case, the 18-MeV betatron-based linear microfocus source generates bremsstrahlung with a spectrum up to the electron energy, while the microfocus X-ray tubes widely used for various purposes have so far reached the photon energy of 750 keV.

Her subsidiary research interests include: theory of solitons. She was a Scientific Researcher from 1969 at Yerevan State University. She has 90 publications in repute journals.

##### Abstract:

It is well known that the motion of dislocation in aluminum takes the quantum regime at low temperatures. It is shown that the action of low temperatures is similar to the action of high Peierls barrier. For description of dislocation phenomena, we used the one-dimensional Frenkel-Contorova (FC) model and sine Gordon equation with and without friction. The (FC) dislocation in aluminum during overcoming Peierls's potential can be considered as topological soliton. The modelling of the dislocation motion process of quantum regime with real constants gives the possibility to investigate the nature of dislocations motion in the Peierls potential, to reveal his radical difference from free movement of dislocations. The theoretical assessment of possibility of the (FC) dislocation motion by means of tunneling is done. The modelling of fields of shifts, speeds and strain-stress dependence at motion of dislocation shows tunneling phenomenon. Thus, the theoretical calculation and mathematical simulation enables us to conclude that if the high Peierls barrier (or low temperatures) is taken into account, the (FC) dislocation is moving by way of kink tunneling. The received results explain abnormal reduction of tension of a plastic current in aluminum at low temperatures.

##### Abstract:

All known string models (Bosonic, Superstring, Heterotic) are formulated in multi-dimensional space-time. To get to realistic and observable four-dimensional world requires a new type of theory. To avoid all inconsistencies, present in known approaches to compactification we propose motley string model, which treats all spacial dimensions equally and complies with a known experimental material. First, we formulate two postulates: Postulate 1: Every spacial dimension of string has a unique intrinsic property which we call color. Postulate 2: There is a force between spacial dimensions of string such that it makes dimensions of complementary colors (Redi, Greeni, Bluei) interact and unite in a colorless thread perceived as observable dimensions. Color property of string's spacial dimensions is somewhat similar to three color charges of quarks in quantum chromodynamics, but has a different meaning, since it is viewed here as intrinsic characteristic of spacial dimensions in motley string theory corresponding to different values of string tension tensor Ti in different dimensions. String state at very high energies (early universe, Planck length about 10-33cm) is such that all string spacial dimensions are in a free state like quark-gluon plasma of quantum chromodynamics. At lower energies (modern universe) strong color force becomes dominant and makes string's complimentary (or using classical optics term "additive") spacial dimensions (Redi, Greeni, Bluei) interact to form three threads (in case of 9+1-dimensional Superstring) which appear to be colorless from distances larger than size of baryons (proton and neutron). Spacial dimensions of additive colors are glued together. Outside of Planck energy scale, spacial dimensions are confined in colorless three-dimensional threads. Since in our model all spacial dimensions are treated uniformly we avoid questions like why some spacial dimensions are compactified while others are not? Also, there are no standing waves in curved dimensions of Klein compactification and therefore no extra mass values (Kaluza-Klein tower). Equally important there is no need for Calabi-Yau and somewhat artificial large extra dimensions models invented to explain unseen spacial dimensions. Motley string model and an idea of colorful spacial dimensions introduced in this article offer consistent and uniform approach to compactification problem present in all String models (Superstring, Bosonic, Heterotic). It eliminates inconsistencies of compactification solutions proposed earlier (Kaluza-Klein, Calabi-Yau manifolds). Also, it explains quark/gluon confinement and many elementary particle generations (6 quarks and 6 leptons) of standard model. At the same time, our model explains dark matter/energy puzzle of modern astrophysics.

###### Title: Deformation quantization of symmetric Kähler manifolds

##### Biography:

Kentaro Hara has completed his Master's degree from Tokyo Metropolitan University. He is pursuing his Doctoral course at the Tokyo University of Science. He has published a paper in reputed journals like *Journal of Geometry and Physics*.

##### Abstract:

A deformation quantization with separation of variables is one of wellknown quantizations of Kahler manifolds. Explicit expressions of the quantization for C^{N} , CP^{N} and CH^{N} were known. We derive algebraic recurrence relations to obtain a deformation quantization with separation of variables for a locally symmetric Kahler manifold. C^{N} , CP^{N} and CH^{N} were locally symmetric Kahler manifolds and Riemann surfaces are also locally symmetric Kahler manifolds. It is not easy to solve the recurrence relations but some are solvable. We found a deformation quantization with separation of variables for Riemann surfaces.

###### Title: Renormalization group improved pQCD prediction for Upsilon(1S) leptonic decay

##### Biography:

Jian-Ming Shen is pursuing his PhD in Chongqing University. His research interests are in Physics at the Large Hadron Collider and other experiments, including precision QCD to improve the standard model prediction and searching for the new physics beyond the standard model. He has published more than 10 papers in reputed journals.

##### Abstract:

The complete next-to-next-to-next-to-leading order short-distance and bound-state QCD corrections to Upsilon(1S) leptonic decay rate has been finished by Beneke et al. Based on those improvements, we present a renormalization group (RG) improved pQCD prediction for the decay width by applying the principle of maximum conformality (PMC). Based on RG-invariance, PMC provides a rigorous method for eliminating renormalization scheme-and-scale ambiguities for perturbative QCD predictions. The PMC scale-setting procedure utilizes the RGE recursively to unambigously identify the occurrence and pattern of nonconformal beta-terms at each order in a pQCD expansion, and determines the optimal renormalization scales by absorbing all occurrences of the beta-terms into the scales of the running coupling at each order of perturbation theory. After applying the PMC, all known-type of beta-terms at all orders, which are controlled by the RG-equation, are resummed to determine optimal renormalization scale for its strong running coupling at each order. We then achieve a scale-fixed, scheme-independent and more accurate pQCD prediction. The pQCD convergence could, in principle, be greatly improved due to the elimination of divergent renormalon terms. The PMC prediction for the Upsilon(1S) leptonic decay reads, 1.270^ {+0.137} _ {−0.187} keV, where the uncertainty is the squared average of the mentioned pQCD errors. This RG-improved pQCD prediction agrees with the experimental measurement within errors, i.e. 1.340(18) keV.

##### Biography:

##### Abstract:

The Big bang, quasi steady state, quantum graviton fluid, internal inflation is not the truth and are not able to define the origin of universe. There was no singularity and the space-time already existed before the universe existed. Our universe is not alone rather there is multiverse. The matter and energy contained presently in our universe cannot be contracted into a very small volume and hence our universe is not from any primordial ball or from any singularity. The different universes are under space-time curvature so the researches like WMAP, Hubble’s law and observatory research by Mr. Wilson and physicist Guth are not capable of determining the other universe. The universe is expanding and is accelerated but the universe will get contracted as space has an elasticity limit. The universe also loses and gains energy during contraction and expansion, but this process is not as usual. It is concluded that space inside which the multiverse lies, and mass-energy equivalence is balanced. No string field responsible for branes is found. Limit of space is supposed where it’s peak point has no effect of time i.e. the space ends here. The entropy will be negative, and the second law of thermodynamics contradicts here. This space has its own inertial resistance. Dark matter is the residue of universe and are made up of fractional neutrinos. I have my own better model describing the origin and end of universe. Here the universe has existence and will end too. The universe is in 4^{th} dimension and none of the existing theories are able to conclude the phenomena of universe. This model can quench the history of the whole system in which the multiverse exist and also the end of universe.
