Nezlin, Mikhail Veniaminovich

Born July 29, 1928 in Gomel , in a family of doctors, one of the representatives of the scientist Nezlin family.
In 1930, the family moved to Moscow, and during the war with his family he was evacuated to Alma-Ata , where he graduated from high school, having passed exams for grades 9 and 10 as an external student.
In 1950 he graduated from the Moscow Power Engineering Institute .
Between 1950 and 1956, he was a researcher, senior engineer of the Sverdlovsk-45 enterprise (he participated in the development of nuclear weapons).
Since 1957, with the support of L. A. Artsimovich, he was admitted to the laboratory of new acceleration methods of the INP SB RAS.
Since 1959 - in the Department of Plasma Research (later the Department of Plasma Physics, and now the Institute of Nuclear Fusion) of the Kurchatov Institute .
Corresponding Member of the Russian Academy of Natural Sciences (1991).
Member of the Editorial Board of the international journal on nonlinear physics “ Chaos ” (USA, 1992-1997).
Member of the Councils of the Russian Academy of Sciences on Plasma Physics and Nonlinear Dynamics, the New York Academy of Sciences , the International Astronomical Union , Planetary and the United States Geographical Societies .
The author of 125 scientific papers and two monographs.

He died on January 1, 1999 .

Scientific activity

Work in the field of plasma physics, geophysical and astrophysical hydrodynamics.
In plasma physics, studies of the strong instability of plasma flows. The first experimentally discovered a new object in plasma physics - the Langmuir soliton in a magnetic field.
He developed a new approach to laboratory modeling of vortex structures in the atmospheres of planets and oceans - a model medium of rapidly rotating shallow water with a free surface in a parabolic vessel. For the first time in the laboratory, a new fundamental object of nonlinear physics was created - the Rossby vortex soliton.
He showed the physical adequacy of the created vortex soliton - anticyclone by the largest long-lived atmospheric vortices dominating on the giant planets: the Great Red Spot of Jupiter , the Great Vortices of Saturn and Neptune . For the first time in a laboratory experiment, the pronounced phenomenon of cyclone-anticyclone asymmetry of Rossby vortices was demonstrated, explaining both the sharp dominance of anticyclones on giant planets and among ocean "lenses", and the relatively fast decay of cyclones. The self-organization of the studied natural vortices and their “long life” in a system of unstable flows with a velocity shift similar to zonal flows in planetary atmospheres have been successfully modeled; using physical modeling, it is shown that with the observed profile of zonal winds on Jupiter, only one anticyclone is generated on the entire perimeter of this parallel of the planet - an analogue of the Great Red Spot.
In experiments on differentially rotating shallow water at two Spiral installations with an unstable rotation velocity profile (similar to the rotation profile of many galaxies), the generation of spiral structures physically similar to the spiral arms of galaxies was first realized. The conclusions of the theory about the generation of spiral arms of galaxies during the development of centrifugal instability caused by the presence of observed jumps in the rotation speed of half of the galactic disks were experimentally confirmed; in particular, the number of spiral arms really turned out to be inversely proportional to the magnitude of the jump.
In addition, at the Spiral installations it was possible to explain the observed phenomenon of “branching” of the spiral arms of galaxies, as well as the reason for the generation of rarely seen “leading” spiral arms, in contrast to the classical “lagging” spirals. Using a model experiment, he predicted the existence of new structures in spiral galaxies - giant anticyclones. A special method for detecting anticyclones has also been developed.
