Biography

Vitaly Kocharovsky has co-authored about 300 papers in refereed journals and proceedings. His scientific interests in theoretical physics and applied physics are very broad and cover a wide range of problems in physics, astrophysics, and cosmology, including: Complex systems and NP-complexity, quantum and nonlinear optics and dynamics, quantum computing, physics of semiconductors and nanostructures, optoelectronics, atomic and molecular physics, quantum electrodynamics including cavity QED, laser physics, fiber optics; generation of radiation in various spectral ranges (microwaves, THz, far/mid/near-infrared, optics, X- and gamma-rays), theory of superradiance and other cooperative coherent processes, plasma physics and electronics, electrodynamics and propagation of waves in inhomogeneous, anisotropic, active or absorbing media (solids, liquid crystals, gases, plasmas, waveguides); physics of nonequilibrium and many-body phenomena, theory of phase transitions and critical phenomena, superconductivity and superfluidity, Bose-Einstein condensation, Ising model, methods of the Green's function and matrix permanent; quantum gravity and quantum field theory, astrophysics of gamma-ray bursts, neutron stars, black holes, extremely high energy cosmic rays, theory of the Universe inflation and Big Bang.
