Kirill Tolpygo
Kirill Borisovich Tolpygo (
Early life
Tolpygo was born during
Education
Tolpygo's life was complicated by being the son of a political prisoner. Nevertheless, he was allowed to enter
Military service
In November 1939, Tolpygo was drafted into the
Scientific career
On returning to Kyiv, Tolpygo restarted work on his PhD thesis and helped in restoring the University. From 1945 to 1966 Tolpygo was teaching theoretical physics at Kiev State University. One of his students was Emmanuel Rashba, who became a prominent theoretical physicist and credited his success in significant part to Tolpygo's guidance and support.[7] From 1963, Tolpygo was Professor of Physics, and from 1960 to 1966 he was Chair of the Department of Theoretical Physics. Concurrently, from 1948 to 1960, he worked as a Senior Scientist at the Institute of Physics of the Academy of Sciences of
In 1966, Tolpygo moved with his family from Kiev to Donetsk, Ukraine. From 1966 to 1988 he worked as Head of the Department of Theoretical Physics at Donetsk Physical-Technical Institute (DonPTI) of the Ukrainian Academy of Sciences and at the same time was Professor and Chair of the Department of Theoretical Physics at Donetsk State University.
Support of dissidents
Tolpygo joined the movement of the "Sixtiers" (shestidesiatniki) and signed a letter to the Soviet authorities in support of dissidents Alexander Ginzburg and Yuri Galanskov. As a result, his position at Kyiv University was jeopardized. At the time, academician Alexander A. Galkin was organizing a new scientific center in Donetsk, Ukraine. His aim was to decentralize scientific research and promote science and technology in regional Ukraine.[8] Galkin convinced Tolpygo to join him in Donetsk and create there a new school of theoretical physics, far from political scrutiny.
Later life
From 1988 to his death in 1994 Tolpygo worked as Principal Scientist at the DonPTI and continued to teach physics at the university. Tolpygo also enjoyed music. He practiced the piano regularly. The
Family life
Tolpygo had four children: Alexey (a mathematician, chess player, and political writer) and Natalia (musician and piano teacher) from his first marriage in 1946 to Oksana Fedorivna Tomasevych, a theoretical physicist, and Sergey (a condensed matter physicist) and Vladimir (a materials scientist), from a second marriage in 1959 to Yelena Isaakovna Kaplunova Tolpygo, also a physicist.
Scientific work
Crystal lattice dynamics and polaritons
Between 1949 and 1956, Tolpygo built a quantum-mechanical theory of
Later, Tolpygo generalized his theory to describe homopolar crystals (Si, Ge, diamond, etc.), cryocrystals of noble gases, and
in alkali halide crystals.Kinetic phenomena in semiconductors
Tolpygo also worked on kinetic phenomena in
surface phenomena, etc.Many-electron theory
Tolpygo also worked on the "many-electron" theory of crystals: development of an efficient method for accounting electron correlations in the
Biophysics
In addition to condensed matter physics, Tolpygo was also interested in biophysics. He proposed an original microscopic theory of muscle contraction based on the idea that the energy of decomposition of adenosine triphosphate (ATP) molecule is transferred along the chains of hydrogen bonds between actin and myosin polymers causing their mutual motion.[33] This theory allowed him to explain experimental features of muscle contraction, such as the relation of tension to velocity as described by Hill's muscle model. He also studied mechanisms of mutations[34] and investigated nonradiative excitations of protons in hydrogen bonds in DNA. He predicted a new quasiparticle – protonic exciton – and investigated its properties.[35]
