Biography

Anatoly Logunov was born in Obsharovka village, now in Privolzhsky District, Samara Oblast, Russia. In 1951 he graduated from Moscow University where he studied theoretical physics. From 1954 to 1956 he worked in Moscow University,[3] later worked at Joint Institute for Nuclear Research (Dubna).[4] He became doktor nauk in 1959 and professor in 1961.[5] In 1968 he was elected a corresponding member of The Academy of Sciences of USSR.[6] In 1971 the department of quantum theory and high energy physics was founded on faculty of physics of Moscow University. Anatoly Logunov was the head of this department right from the start at least until 2006.[2] In 1972 Anatoly Logunov was elected an academician in the field of nuclear physics.[7] From 1977 till 1992 he was the Rector of Moscow University. Anatoly Logunov died on 1 March 2015 in Moscow, Russia.[4] He was buried at Troyekurovskoye Cemetery in Moscow.

Research

Logunov made a notable contribution to theory of gravity.[8][9] He studied quantum field theory.[10] In 1956 he built generalized finite multiplicative renormalization groups and functional and differential renormalization group equations of electrodynamics in case of arbitrary calibration.[2][11] Jointly with Piotr Isayev (Russian: Петр Степанович Исаев), Lev Soloviov (Russian: Лев Дмитриевич Соловьев), Albert Tavkhelidze (Russian: Альберт Никифорович Тавхелидзе) and Ivan Todorov (Bulgarian: Иван Тодоров) et al. he derived dispersion relations for different processes of elementary particle interactions, among them the processes of photobirth of ${\displaystyle \pi }$ -mesons in nucleons.[12] He studied Bell's spaceship paradox,[13] the ideas of Henri Poincaré.[14]

Relativistic theory of gravitation

After studying works of Poincare, Lorentz, Hilbert and Einstein in great detail, Logunov and his colleagues developed the relativistic theory of gravitation (RTG), a theory of gravitation alternative to that of the general theory of relativity.[15][16] RTG is constructed in the framework of the special theory of relativity. It asserts that gravitational field, like all other physical fields, develops in Minkowski space, while the source of this field is the conserved energy-momentum tensor of matter, including the gravitational field itself. This approach permits constructing, in a unique and unambiguous manner, the theory of gravitational field as a gauge theory. Here, there arises an effective Riemannian space, which literally has a field nature.[17][18] Unlike General Relativity (GR), according to which space is considered to be Riemannian owing to presence of matter and gravity is considered a consequence of space-time exhibiting curvature, the RTG gravitational field has spins 2 and 0 and represents a physical field in Faraday-Maxwell spirit. In RTG, unlike GR, the energy-momentum and the angular momentum conservation laws are fulfilled. Moreover, analyses of the development of a homogeneous and isotropic Universe within RTG leads to the conclusion that the Universe is infinite, and that it is "flat". It evolves cyclically from a certain maximum density down to a minimum and so on. Thus, no pointlike Big Bang occurred in the past. There existed a state of high density and high temperature at each point in space. The theory also predicts the existence in the Universe of a large hidden mass of "dark matter" and impossibility of infinite gravitational collapse (no black holes).[15][19][20]
