He is the author of more than 300 scientific works.
The scientific interests of the theoretical physicist cover a wide range of problems. Among them are the problems of philosophy of science, astrophysics and geophysics, cosmology, statistical physics, quantum theory, in particular the theory of quantum liquids, the theory of phase transitions, physics of disordered systems.
His most significant works in quantum theory include his work on the theory of superfluidity, the phenomenon that was discovered in 1938 by Peter Kapitsa, the phenomenon observed in liquid helium at temperatures close to absolute zero and in which the main role is played by quantum effects. With the help of his new microscopic theory of Bose liquids, created by him in the 90's, for the first time from the first principles, the transition due to Bose-Einstein condensation has been described, the main mechanisms of the influence of interatomic interaction on this phenomenon and the concrete manifestations of its connection with λ-transition. A peculiar culmination of studies of the phenomenon of superfluidity was the calculation of the critical temperature of the Bose-Einstein condensation and the thermodynamic functions of the Bose condensate.
Using the method of two-time Green's functions, he built a microscopic theory of disordered systems, which allows the only way to describe the basic manifestations of structural disorder and their dependence on external influences (fields, pressure, temperature, etc.). His works on critical phenomena and the development of microscopic methods statistical descriptions, cause an interest in the scientific world.
Of special importance in the field of astrophysics is its microscopic theory of stellar spectra, which allowed to predict new physical effects associated with the mechanism of formation of frahungfer lines.
