Yuri Antonovich Simonov

from Wikipedia, the free encyclopedia

Juri Antonowitsch Simonow , Russian Юрий Антонович Симонов , English transcription Yuri Simonov, (born June 6, 1934 ) is a Russian theoretical physicist. He was head of the laboratory for theoretical nuclear physics at the Institute for Theoretical and Experimental Physics (ITEP).

Simonov studied at the Moscow Institute of Physics and Technology (MIPT), graduating in 1958 with I. Yu. Kobzarev and then worked with Karen Avetowitsch Ter-Martirosjan and Isaak Jakowlewitsch Pomeranschuk at ITEP. In his diploma thesis with Kobzarev at the MIPT, he theoretically dealt with parity violation in the weak interaction, which was overtaken by the work of Tsung-Dao Lee and Chen Ning Yang . As a student of Pomerantschuk, he kept in close contact with experimental physicists and in the 1960s gave lectures for experimental physicists on the determination of the quantum numbers of resonances in high-energy physics. He also dealt with dispersion relations and expanded here the formulas of Stanley Mandelstam and Regge-Poland , treating them with the Bethe-Salpeter equation . In the mid-1960s he changed research areas. He dealt with few-particle systems, for example in nuclear physics, and developed an alternative to the treatment of the quantum mechanical three-body problem by Ludwig Faddejew by developing according to hyperspherical functions (K harmonics). In 1967 he applied the method to nuclei with four nucleons. His investigations into the binding energy of light nuclei led him to the conclusion at the beginning of the 1970s that the usual nuclear interactions were unsuitable and that new internal degrees of freedom of the nucleons (quarks) were ultimately necessary, which he explained in the late 1970s in the case of nucleon-nucleon- Investigated scattering with quark degrees of freedom. In the 1970s he also developed a general theory of multichannel scattering processes in nuclear and particle physics based on unitarity and analyticity considerations, and he dealt with solitons. Later he dealt with the non-perturbation theoretical description of phenomena of QCD using gauge-invariant non-local correlators.

In 2016 he received the Pomeranchuk Prize with Curtis Callan . He received it for a new method for describing non-perturbation-theoretical effects in quantum chromodynamics based on vacuum correlation functions.
