##### Abstract:

Nuclear internal electronic conversion (NIC) is the transfer of nuclear excitation energy DЕ to atomic electron and formally is described by the same Feynman diagram as the elastic scattering of two free charged particles. But these processes differ from each other by the character of particles interaction with electromagnetic (EM) field. In the elastic scattering the interchange of energy DЕ between particles in general does not fix the frequency w of virtual photons and the scattering amplitude depends on intensity I(w) of zero-point quantum fluctuations of EM field and photons in the scattering region in wide frequency range, and not only at the transition frequency DЕ=hw_{res}. In contrast, as it is shown in the present work, because only the discrete nuclear energy levels are taking part in NIC and always their half-life T_{1/2}>>h/DЕ, NIC probability is proportional to the intensity I(w_{res}) of the EM field modes near resonant frequency w_{res} only. So, NIC is stimulated by EM field as in the same fashion that the transition with γ-quantum radiation and for instance in γ-laser the NIC stimulation would compete with the γ-radiation stimulation. Such resonant character of NIC leads to the suppression of low energy NIC inside metallic matrix because the matrix can suppress zero-point EM fluctuations at resonant frequency w_{res}. By such way can be explained the observed strong suppression of NIC for nuclear isomers ^{235m}U (DЕ=76 eV), ^{154m}Eu (DЕ=910 eV) and ^{99m}Tc (DЕ=2.17 keV) inside metallic matrixes.

###### Title: Experimental manifestation of the residual strong nuclear interaction via renormalization of the elementary excitations energy of solid

Time : **12:30 - 13:00**

##### Biography:

##### Abstract:

When nuclear physics developed, two new short – ranged interactions joined to the well – known long – ranged interactions of the gravitational and electromagnetic forces. These are nuclear force, which acts between nucleons (protons, neutrons) and weak force which manifests itself in nuclear β – decay. The nuclear force is a result of the residual strong force binding quarks to form protons and neutrons. There is a common place in contemporary physics that the strong force does not act on leptons. Our experimental results show the violation of this strong conclusion. Until now macroscopic manifestation of the strong nuclear interaction are restricted to radioactivity and the release of nuclear energy. Our report is devoted to the description of the significantly new kind manifestation of the residual strong force. We have studied the low – temperature (2 K) optical spectra (luminescence, reflection and scattering of light) of the LiH and LiD crystals which differ by term of one neutron from each other. In dielectrics crystals an electron from valence band (Fig. a) is excited into conduction band. The attractive Coulomb potential between the missing electron in valence band, which can be regarded as a positively hole, and electron in conduction band forms exciton which energy E_{n} _{=1s}_{g} is the energy of the band – to band transition (Fig. a). As demonstrated early most low – energy electron excitation in LiH (LiD) insulating crystals are large – radius excitons. In our experiment, we used samples with clean surface cleaving the crystals in the bath of helium cryostat with normal or superfluid helium. Free exciton luminescence is observed when studied crystals are excited in the midst of fundamental absorption. The spectrum of free exciton luminescence of LiH (LiD) crystals cleaved in superfluid helium consists of narrow phononless emission line and its broader phonon replicas which arise due to radiative annihilation of excitons with the production of one to five LO phonons (Fig. b). At the adding one neutron (using LiD crystals instead LiH ones) is involved the increase exciton energy on 0.103eV. As far as the gravitation, electromagnetic and weak interaction are the same of both kind crystals it only changes the residual strong interaction therefore a doubtless conclusion is made that the renormalization of the energy of electromagnetic excitation (excitons, phonons) is carried out by the residual strong nuclear interaction. According to quantum chromo dynamics electric – like color forces should be confined inside nucleons given that gluons have their emission and absorption in individual colored quarks. On the other hand, perhaps magnetic – like strong fields are by their very nature difficult to be contained within nucleons and may be could be acting, at least in principle, far beyond nucleon realm. Thus, the direct observation of residual strong nuclear interaction in the optical spectra of solids opens a new avenue in nuclear and elementary particles physics.

##### Abstract:

Despite the formal disappearance of spin in classical limit n ̶˃0 the concept of classical charged magneton found numerous applications in high energy physics of polarized beams. The radiation effects such as spin light and radiative polarization (RP) are usually treated as being purely quantum in nature. Nevertheless, the analysis of Novosibirsk 1984-year experiment have shown that full understanding of spin light phenomenon could be achieved through the use of classical Frenkel model (FM). Within the given approximations the principal deviation of FM from the widely used Bargmann–Michel-Telegdi model lies in the field-dependent addition to the electron mass. The latter is responsible for the unusual sign of the spin contributions to the rate and power of synchrotron radiation. This inertial spin effects seems to be a universal property of the charged magneton-type systems. The wide class of the models descriptive of those systems employs the Grassmann algebra to represent (pseudo) classical spin degrees of freedom. We show that spin and trajectory equations of FM could be reconciled with the appropriate equations of pseudoclassical Berezin–Marinov model after the procedure of averaging over Grassmann variables have been applied. Within a classical approach we give also a brief discussion of RP phenomenon considering its possible relation to ‘circular Unruh effect’.

Independent Researcher, Switzerland

###### Title: Special and general relativity and the relativistic ether as observer dependent by the retardation

##### Biography:

Azzam Almosallami is a Theoretical Physicist based out of Zurich, Switzerland. He has published many articles and researched on many theories. His research was published in a journal and it is well known among most of the professors in physics. It was discussed in research gate since four years and succeeded in his paper in quantization of gravity. Because of that the discussion about relativity SRT and GR is almost closed. With the help of his theory, he could solve all the problems in physics very easily.

##### Abstract:

In this paper I’ll show how the relativistic effect in SRT must be observer dependent which is leading to field and retardation, and that is leading to the wave-particle duality and the uncertainty principle by the vacuum fluctuation. In this I propose a new transformation by translating the retardation according to the invariance by the entanglement which is leading to the relativistic ether from the point of view of the quantum vacuum which is leading to the wave-particle duality and the uncertainty principle by the vacuum fluctuation. According to my transformation, there are two pictures for the moving train, and these two pictures are separate in space and time as a result of the retardation but they are entangled by the invariance of the energy momentum. That will lead also to explain the double slit experiment from the point of view of quantum theory. In my new transformation, I propose there is no space-time continuum, as in special relativity; it is only time, and space is invariant. That leads to the new transformation being vacuum energy dependent instead of relative velocity dependent as in Einstein’s interpretation of the Lorentz transformation equations of the theory of special relativity. Furthermore, the Lorentz factor in my transformation is equivalent to the refractive index in optics. That leads to the disappearance of all the paradoxes of the theory of special relativity: The Twin paradox, Ehrenfest paradox, the Ladder paradox, and Bell’s spaceship paradox. Furthermore, according to my interpretation, one could explain the experimental results of quantum tunneling and entanglement (spooky action), Casimir effect, and Hartman effect. Also according to that by my equivalence principle, dark matter and dark energy are explained, and no need to propose dark matter and dark energy, and as a consequence of that, the cosmological constant problem will be solved.

###### Title: A new approach to the generalization of planck’s law of black-body radiation

##### Biography:

Sreeja Loho Choudhury has completed her Bachelor’s degree in Physics from St. Xavier’s College, Ahmedabad, India. She did her Master’s degree in Physics from Birla Institute of Technology, Mesra, Ranchi, India. She has now joined her PhD at the Institute for Theoretical Physics, Technical University in Dresden, Germany in the month of April, 2018. She is working in the Field of Atomic and Molecular Physics, and her Master’s thesis was about generalizing the Planck’s law of Radiation and Applying It to Plasma Physics. Her Bachelors thesis was about studying the Effect of Charge-State Ratios on the Flow of Solar Wind.

##### Abstract:

In this study, Planck’s law of black-body radiation has been modified within the framework of nonextensive statistical mechanics. The average energy of radiation has been derived by introducing the nonextensive partition function in the statistical relation of internal energy. The spectral energy density and spectral radiance have also been computed. The derived expression has been compared with the earlier developed approximate schemes (i.e. asymptotic approach and factorization approach) and with the recently obtained exact result. We utilize the exact and approximate Stefan-Boltzmann laws in order to compare with the new approach introduced here.

##### Abstract:

Models for biological membranes are essential to address fundamental studies regarding membrane-membrane interaction, the functionality of proteins, the dynamics of ions through the membrane and its structure in itself. Maintaining the membrane hydrated, fluidic and close to the substrate without cumbersome chemistry can be a challenge. Here, we develop a new experimental approach where a single model phospholipid bilayer is kept fluid and partially tethered to a flat electrode. We proposed an original anchoring surface functionalization that is highly reactive to –OH terminated molecules. In this way we avoid complex organic chemistry and graft commercial Brij non-ionic surfactants chosen for: their appropriate hydrophilic chain length that forms an aqueous cushion for the membrane; their hydrophobic alkyl block that anchors the lipid bilayers by insertion in their core. In this way, we keep the membrane fluidity in full immersion and presence of salts. This method appears to be a simple and cheap way to prepare tethered membranes with tunable anchoring densities on various supporting materials. Using transparent electrodes (ultra-flat and thin metal layers on glass), we could check the membrane fluidity and lipids dynamics from fluorescence techniques (such as *in-situ* FRAP for measuring the lateral diffusion of inserted fluorescent lipids). The transparent electrodes are also designed for high-resolution structure investigation of the single membrane using x-ray, neutron and light scattering methods (microscopies, surface plasmon resonance, fluorescence). Tethering the bilayer on conducting substrates also open avenues for the use of cheap and easy to build membrane biochips for biotechnological applications.

##### Abstract:

We obtained an exact algebraic solution for the quantum harmonic oscillator with variable frequency in a closed form. This allows us to implement a numerical calculation to study the dynamics of the system. It is shown that for any frequency function, the instantaneous state of the system is a squeezed one of the initial Hamiltonian. Once the final state is found, is mandatory to analyse the models that maximize the squeezing degree. We present a discussion by comparison of the Janszky-Adam scheme, where the frequency modulation accounts through sudden changes between two stable frequencies, and the parametric resonance model, where the frequency modulation accounts through a harmonic function. In such analyses new aspects of the problem are elucidated.
