Biography
Born October 15, 1955. The twin brother of the physicist Vitaly Vladilenovich Kocharovsky .
In 1978, he graduated with honors from the Radiophysical Department of UNN . Since 1978 he has been working at the Institute of Applied Physics of the Russian Academy of Sciences . Since 2011, head of the department of astrophysics and space plasma physics.
Since 1987 he has been teaching at the Nizhny Novgorod State University . He taught courses in Electrodynamics, Thermodynamics and Statistical Physics, Nonlinear Field Theory, Plasma Astrophysics, and Contemporary Problems of Physics. Since 2012 - professor of UNN.
In 1986 he defended a thesis for the degree of candidate of physical and mathematical sciences in radiophysics at the Scientific Research Radiophysical Institute .
In 1998 he defended his thesis for the degree of Doctor of Physics and Mathematics in quantum electronics . The topic of the dissertation is “Mode superradiance in open resonators and extreme modes of electromagnetic field generation by ensembles of quantum and classical oscillators”.
In 2006, he was elected a corresponding member of the Russian Academy of Sciences in the Department of Physical Sciences .
Scientific achievements
V.V. Kocharovsky is a specialist in the field of theoretical physics and astrophysics and has contributed to solving problems in many areas of physics.
In the field of radiophysics, he constructed the theory of linear interaction of waves in inhomogeneous anisotropic media, which is now used in the polarization diagnostics of media.
In the field of low temperature physics , the formation of electron pairs was predicted due to Bragg-Coulomb pairing. This mechanism can lead to the observation of high-temperature superconductivity in layered compounds. The properties of the quasiparticles of the canonical Gibbs ensemble in the Bose - Einstein condensate were studied. The results of this work allow us to describe the dynamics of condensate formation and predict abnormally large non-Gaussian fluctuations in the number of particles in it.
In the field of quantum optics , a method has been developed to describe the phenomenon of superradiance as a dissipative instability of waves of negative energy. The existence of this phenomenon was predicted not only in quantum, but also in classical systems, as well as in semiconductors .
In the field of quantum electronics , a new type of semiconductor lasers has been proposed and implemented - transistor and interband cascade lasers . Such lasers are used to generate two-frequency optical radiation, as well as radiation in the far infrared range .
In plasma physics and astrophysics , an analytical theory of the self-consistent synchrotron and inverse Compton radiation of relativistic electrons was constructed. This made it possible to predict the existence of annihilation-cyclotron lines in the gamma-ray spectrum of neutron stars . In a relativistic plasma , a new class of solutions has been constructed, which are current layers and filaments. A mechanism for accelerating charged particles was proposed, based on the multiple transition of particles from a charged state to a neutral state and vice versa. This mechanism made it possible to explain the origin of cosmic rays of superhigh energies.
