Synchronous Dynamics of Nephrons Ensembles

Authors: Pavlova O. N., Anisimov A. A., Nazlmov A. I., Alexyi A. N.

In this work, the phenomenon of synchronization of oscillations in the dynamics of nephronic ensembles is studied. It is shown that a large number of structural units on the kidney's surface participate in the formation of synchronous clusters. It is stated that the cluster's size changes in time and the frequency locking for rhythmic processes in the cooperative dynamics of nephrons occurs only during some parts of experimental recordings. 

Non-Stationary Coherent Population Trapping in Frequency-Modulated Fields

Authors: Derbov V. L., Plastun I. L., Orudjev A. A.

Coherent population trapping (CPT) resonance formation is modeled numerically in a three-level Λ-system with one of the near-resonance fields being frequency-modulated. The model is based on density matrix equations in RW approximation with atomic relaxation properly taken into account. Slow modulation is shown to be equivalent to CW excitation with the frequency changed point by point.

Spatio-Temporal Dynamics of Modulated cw Laser Beam in Spatial-Extended Nonlinear Medium

Authors: Plastun I. L., Misyurin A. G.

On the basis of spatio-temporal numerical model the dynamics of frequency-modulated cw laser beam propagating in resonance conditions is investigated. At modulation periods comparable with the atomic relaxation times the time and frequency dependence of the output intensity exhibits the manifestations of delayed medium response and resonance self-action. Time dependence of output intensity and spot size are measurement parameters. On the basis of phase portraits and power spectrum analysis we found a different dynamical regimes.

Authors: Zayko Y. N.
This article is a continuation of the previous author's article on the same problem [1], Here choice of metrics discusses in detail, so as another possible metrics, like generalization of the Schwarzschild metric of massive body due to radiation of electromagnetic wave. A problem of lowering the initially spherical symmetry to axial one in solution’s level for Einstein−Maxwell (or Maxwell) equations due to fixation of z-axis of coordinate system and its recovery with the help of zero-modes is discussed.

Model of the Processes Nanostructure Formation during Plasma Spraying Hydroxyapatite Porous-Powder Coatings

Authors: Lyasnikova A. V., Antonov I. N., Lyasnikov V. N.

We offer a physical model of the process nanostructure formation during plasma spraying hydroxyapatite coatings and described the thermodynamics of heating particle in the plasma torch. We analyzed thermal processes on the base and the formation of thermal fields in the system particle-base by plasma spraying. Possibly that the formation of amorphous coatings, consisting of submicron particles, happened because shear through by contact with the material and base and nanosized crystals appear as a result of very fast cooling (quenching) of the submicron structures.

Why the Refractive Index Couldn't Be Negative

Authors: Davidovich M. V.
It had been shown that for left-handed metamaterials and generally for negative refraction media the refraction index could not be introduced uniformly and could not be considered as real, especially as negative. This index for above referred media is not expedient.

SN and СМВ Data and Higgs Particle Mass in a Scale-Invariant Gravitation Theory

Authors: Pervushin V. N.

In a Scale-Invariant Gravitation Theory, it was shown that both CMB data and SN ones testify to an ordinary cosmological quantum vacuum creation of the Universe together with the W-, Z-vector bosons and the Higgs particles. The initial momentum of the evolution, given by the kinetic energy of an additional scalar field, the Standard Model mass spectrum determine the CMB temperature and its fluctuation spectrum, if the Higgs particle mass is in the region of about 118 GeV.

Superextensions of Landau Models

Authors: Ivanov E. A.

The paper is a review of recent works on superextensions of the model of non-relativistic quantum charged particle moving in a homogeneous magnetic field on the plane R2 (Landau model), and a model of the particle in the field of Dirac monopole on the sphere S2: SU(2)11/(1) (Haldane model). We consider the models on the supersphere Sl/(2|1)/l/(1|1), superflag SU(2|1)/[l/(1)xl/(1)] and their planar limits, based upon a geometric interpretation of these models and their bosonic proptotypes as d=1 analogs of nonlinear sigma models of the Wess-Zumino-Novikov-Witten type.

Coherent States and Mode Dynamics in Kerr Nonlinear Medium

Authors: Barsov A. S., Gorokhov A. V.

Dynamics of three photonic modes in the theory of parametric amplifier in the medium, taking into account the Kerr nonlinearity, can be studied using the dynamical group WSp (6, R). For a degenerate parametric amplification with classical pump the description is reduced to the dynamics of coherent states of SU(1,1) group. The time dependence of average numbers of photons and squeezing are calculated. It is shown that the «switching-on» of the Kerr nonlinearity leads to suppression of the parametric amplification.

Non-Markovian Quantum Relaxation and Theory of Spectral Lines Width

Authors: Gorokhov A. V., Semin V. V.

The quantum equation of relaxation with non-Markovian terms in the approximation of short-time memory is derived. The correlation functions for a single two-level atom and system of two dipole-dipole interaction of atoms in the external regular fields and the contour of the radiation lines are calculated. Accounting Non-Markovian effects leads to a more vivid expression of dipole-dipole interaction.

Exactly Solvable Model of Instantaneously Switched-On Field In the Kinetics of Vacuum Particle Creation

Authors: Blaschke D. B., Dmitriev V. V., Smolyansky P. I., Smolyansky S. A., Chertilin A. V.
Exact solutions of the nonperturbative kinetic equations for the description of fermion and boson pair creation in the vacuum are obtained for the case of a linearly polarized instantaneously switched-on electric field. The corresponding momentum distributions are nonintegrable, The renormalized distribution functions are also found. The obtained results can be used as estimates for upper limits of different vacuum pair creation effects in the more realistic case of short electric field pulses.

Authors: Zayko Y. N.

This article concerns the effect of gravitation field of the spherical electro-magnetic wave (EMW) on its propagation in vacuum. For this it was received a solution of the coupled Maxwell-Einstein equations. The expression for metric is supposed to be just the same as in wellknown Schwarzschild problem for gravitation field at the vicinity of point mass with additional dependence on polar angle 9. The equations for radial and angular parts of EMW fields of ТЕ- and TM-types are received. Their various solutions are Investigated.

Dynamical Chaos In Quantum Systems

Authors: Lazerson A. G., Boykov A. A.

Complex dynamics of a quantum periodically driven square well is considered. It is shown that analysis of its ensemble average energy time series provides an identification of its dynamics to be either regular or chaotic. It has been found that enhancement of the driving force causes the energy spectrum to look like a spectrum of some random process, which may be identified as the signature of chaos in a quantum system.
