## Biography

A. L. Kuzemsky graduated from the Faculty of Physics (1963-1969) of the Moscow State University named after MV Lomonosov (Moscow State University). In 1967-1969 entered and studied at the department of the theory of the atomic nucleus, headed by Professor Dmitry Ivanovich Blokhintsev (1908-1979) in the city of Moscow and Dubna. In December 1968 he defended his thesis at the Department of the Theory of the Atomic Nucleus on the theme of the *theory of a ferromagnetic crystal with two spins in a node* (scientific supervisor Prof. Corresponding Member of the Academy of Sciences of the USSR L. A. Maximov, I. Kurchatov IAE ). Since February 1969, he has been employed at BLTP JINR as a trainee researcher in the sector of statistical physics, previously headed by prof. S.V. Tyablikov (1921-1968). In December 1970, he defended his thesis on the topic of the *Application of the Nonequilibrium Statistical Operator Method to the Theory of Solid Orthohydrogen* (the supervisor was Prof. D. N. Zubarev (1917–1992)). In 1985 he defended his doctoral thesis on the topic *Microscopic Theory of Correlation Effects in Transition Metals and Alloys* (Bogolyubov Laboratory of Theoretical Physics, Joint Institute for Nuclear Research, Dubna). Currently working as a leading researcher at the Laboratory of Theoretical Physics. N. N. Bogolyubova, Joint Institute for Nuclear Research, Dubna. In 1987–1997 He was a member of the Board of the Moscow Physical Society, a member of the editorial board of the *Journal of the Moscow Physical Society* . Delegate from Dubna at the first constituent congress of the All-Union Physical Society. Member of the Magnetic Society of the Russian Federation. A. L. Kuzemsky devotes time and pedagogical work, supervises the graduation works of students. Repeatedly, the work carried out under his leadership occupied the first places at all-Russian contests. This activity was awarded a special diploma of the Ministry of Education of the Russian Federation in 2000 . The appeal date is November 13, 2011. Archived December 10, 2012. . A. L. Kuzemsky is the author of more than 210 scientific papers and about 30 publications on general issues of science, the relationship of physics and philosophy, and so on. About 10 articles were published in the newspaper *DUBNA.* *The science.* *Commonwealth* *Progress*

The main works of A. L. Kuzemsky are devoted to statistical physics and the quantum theory of solids. His interests include fundamental questions of the physics of magnetism, methods of the quantum theory of magnetism and, in particular, the method of two-time temperature Green's functions, widely used in various problems of physics of systems of many interacting particles. He considered a range of problems in the quantum theory of solids, in particular, the construction of a consistent quantum-static theory of magnetism and superconductivity of complex substances based on the approximation of strongly bound electrons.

A. L. Kuzemsky developed an effective self-consistent method for describing strongly interacting Fermi systems on a lattice. The method was used to describe quantum cooperative effects and quasiparticle dynamics of the main microscopic models of magnetism: Heisenberg models, Hubbard models, Anderson models, spin-fermion models, etc. A comparative analysis of these models and their applicability to the description of complex magnetic substances was carried out.

In the framework of the nonequilibrium statistical operator method D. N. Zubareva, the conclusion of generalized kinetic equations for a system in a thermal bath is given. The dynamic behavior of a particle in a medium was studied taking into account the effects of dissipation. In this case, a generalized equation of the Schrödinger type was obtained, which describes the motion of a particle in a medium with friction.

AL Kuzemsky continues the scientific work devoted to the methods and models of the quantum theory of many bodies. He published 2 monographs on this subject. In the book published by the JINR Publishing House in 2009: A. L. Kuzemsky, *WORK ON STATISTICAL PHYSICS AND QUANTUM THEORY OF A SOLID BODY* , a concise, but detailed and publicly available presentation of these works is given. He also published 20 reviews on various issues of the quantum theory of solids, including reviews of the works of Dmitry Ivanovich Blokhintsev and Nikolai Nikolaevich Bogolyubov . In 2008–2009 Kuzemsky took an active part in the preparation and commenting of the two-volume work of DI Blokhintsev's Selected Works (Fizmatlit, Moscow, 2009). In 2017 he published a fundamental monograph: *Statistical Mechanics of Many-Particle Model Systems* (World Scientific, Singapore, 2017) 1260 p., ISBN: 978-981-3145-62-7; http://www.worldscientific.com/worldscibooks/10.1142/10169
