In the renormalization group analysis of phase transitions in physics, a critical dimension is the dimensionality of space at which the character of the phase transition changes.
 Below the lower critical dimension there is no phase transition.
 Above the upper critical dimension the critical exponents of the theory become the same as that in mean field theory.
 An elegant criterion to obtain the critical dimension within mean field theory is due to V. Ginzburg.
Eduard Alekseevich Kuraev (Russian: Эдуа́рд Алексе́евич Кура́ев; October 17, 1940, Apsheronsk – March 4, 2014, Dubna) — Soviet and Russian theoretical physicist.
 Doctor of Physical and Mathematical Sciences (1971).
Ludvig Dmitrievich Faddeev (also "Ludwig Dmitriyevich"; Russian: Лю́двиг Дми́триевич Фадде́ев ; 23 March 1934 – 26 February 2017) was a Soviet and Russian theoretical physicist and mathematician.
 He is known for the discovery of the Faddeev equations in the theory of the quantum mechanical three-body problem and for the development of path integral methods in the quantization of non-abelian gauge field theories, including the introduction (with Victor Popov) of Faddeev–Popov ghosts.
 He led the Leningrad School, in which he along with many of his students developed the quantum inverse scattering method for studying quantum integrable systems in one space and one time dimension.
 This work led to the invention of quantum groups by Drinfeld and Jimbo.
Yuri Petrovich Raizer (Russian: Юрий Петрович Райзер, born January 26, 1927 in Kharkiv, USSR) is a prominent Soviet and Russian theoretical physicist.
 He received his PhD degree in 1953 and his Doctor of Sciences degree in 1959.
 He is Senior Research Fellow with Ishlinsky Institute for Problems in Mechanics of the Russian Academy of Sciences, Moscow, Russia where he has been serving as a head of the Division of Physics of gas dynamic processes since 1965.
 Additionally, he has been professor at the Moscow Institute of Physics and Technology since 1968.
Anatoliy Sazonovich Koroteyev (Russian: Анато́лий Сазо́нович Короте́ев ; born Jule 22, 1936) is a Soviet and Russian theoretical physicist
Kirill Gurov (March 6, 1918 in Moscow – September 29, 1994) was a Soviet Russian theoretical physicist working in the field of physical kinetics.
Viatcheslav Fyodorovich Mukhanov (Russian: Вячесла́в Фёдорович Муха́нов ; born October 2, 1956) is a Soviet/Russian theoretical physicist and cosmologist.
 He is best known for the theory of Quantum Origin of the Universe Structure.
 Working in 1980-1981 with Gennady Chibisov in the Lebedev Physical Institute in Moscow he predicted the spectrum of inhomogeneities in the Universe, which are originated from the initial quantum fluctuations.
 The numerous experiments in which there were measured the temperature fluctuations of the Cosmic Microwave Background Radiation are in excellent agreement with this theoretical prediction, thus confirming that the galaxies and their clusters originated from the initial quantum fluctuations.
 Later on V. Mukhanov proved that the results, he obtained with G. Chibisov in 1981, are of the generic origin and he has developed the general consistent quantum cosmological perturbation theory.
Vitaly Lazarevich Ginzburg, (Russian: Вита́лий Ла́заревич Ги́нзбург ; 4 October 1916 – 8 November 2009) was a Soviet and Russian theoretical physicist, astrophysicist, Nobel laureate, a member of the Soviet and Russian Academies of Sciences and one of the fathers of the Soviet hydrogen bomb.
 He was the successor to Igor Tamm as head of the Department of Theoretical Physics of the Lebedev Physical Institute of the Russian Academy of Sciences (FIAN), and an outspoken atheist.
Anatoly Alekseyevich Logunov (Russian: Анатолий Алексеевич Логунов , December 30, 1926 – March 1, 2015) was a Soviet and Russian theoretical physicist, academician of the USSR Academy of Sciences and Russian Academy of Sciences.
 He was awarded the Bogolyubov Prize in 1996.
Yuri Andreevich Yappa (Russian: Юрий Андреевич Яппа ) (September 21, 1927 – August 19, 1998) was a Soviet and Russian theoretical physicist.
 He is known for publications on particle physics, quantum field theory, General Relativity, philosophy of science, and for his graduate texts on classical electrodynamics and theory of spinors.
