Valery Leonidovich Pokrovsky
Valery Leonidowitsch Pokrovsky ( Russian Валери Леонидович Покровский , English transcription Valery L. Pokrovsky; * 1931 ) is a Russian physicist. He is Professor of Theoretical Physics at Texas A&M University and a scientist at the Landau Institute for Theoretical Physics .
Valery Pokrovsky studied physics in Kharkov (Ukraine), where he graduated in 1953, and received his doctorate in 1957 from Tomsk University . His teachers included Lifschitz and Achijeser . Afterwards he was a teacher at a technical school in Novosibirsk for 13 years , where he also received his doctorate under Rumer in 1957 (at the University of Tomsk). From 1957 he was at the Institute for Radiation Physics and then the Institute for Semiconductor Physics of the Siberian Department of the Soviet Academy of Sciences. He also gave lectures at the Novosibirsk University . Since 1966 he has been researching at the then newly founded Landau Institute for Theoretical Physics in Chernogolowka near Moscow , combined with a professorship for Theoretical Physics at the Moscow Institute for Physics and Technology . He has been a professor at Texas A&M University since 1992 (he was appointed distinguished professor in 1998 ).
His scientific work focuses on statistical physics and solid state physics . Particularly noteworthy are his early fundamental contributions, around 1965, to the modern theory of phase transitions (scaling of the correlation functions near critical points), together with Alexander Pataschinski , as well as his analysis of phase transitions between commensurable and incommensurable phases in two-dimensional systems, together with Andrei Talapov ( Pokrovsky -Talapov transition ). Most recently (2005) he deals with the influence of noise on Landau-Zener tunnels and materials with ferromagnetic and superconductor properties at the same time.
In 1963, together with Patashinski and Isaak Chalatnikow , he developed a non- perturbation- theoretical method for semiclassical scattering problems on potential wells in quantum mechanics (using Regge Poles).
Pokrowski's excellent research is u. a. Honored twice with the Landau Prize of the Academy of Sciences of the USSR (1984, 2018), the Humboldt Prize of the German Research Foundation (2000) and the Lars Onsager Prize of the American Physical Society (2005), of which he became a fellow in 1999 been.
