Research work

His first research in Arzamas-16 was devoted to various applications of plasma
Plasma (physics)
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. Heating a gas may ionize its molecules or atoms , thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions...

 theory, including analyzis of stationary regimes for nuclear reactors (jointly with V. N. Klimov) and analysis of temperature jumps of plasma in magnetic field.

After that he started to work in collaboration with Nikolay Bogoliubov on various problems in theoretical physics and obtained several fundamental results, including development of an asymptotic method for systems with rapidly rotating phases, development of the method of collective variables which is now widely used in theoretical physics, and development of the microscopic theory of superfluidity.

He made a significant contribution to the theory of double-time temperature Green's functions

 in statistical mechanics, where his work became world famous.

In the period 1961—1965, he developed a method of non-equilibrium statistical operator (NSO), which is now a classical tool in the statistical theory of non-equilibrium processes. This method allowed him to include non-equilibrium phenomena in the framework of statistical mechanics in a natural way following the ideas of Josiah Willard Gibbs
