Alexander Davydov

Alexander Davydov ( _ua. Олександр Сергійович Давидов; December 26 1912, Eupatoria - 1994, Kiev) was Soviet and Ukrainian physicist.

Biography

Davydov graduated from the Moscow University in 1939. In 1963-1990 he was Director of Institute for Theoretical Physics of the Ukrainian Academy of Sciences.

His main contributions were in theory of absorption, scattering and dispersion of the light in molecular crystals. He predicted the phenomenon that is known as "Davydov splitting" in 1948. He also worked in theory of collective excited states in spherical and non-sperical nuclei, known as Davydov-Filippov Model and Davydov-Chaban Model (1958-1960). The conception of molecular solitons to originally explained mechanism of muscle contraction of animals was applied (1973-1974). Theoretically studies the interaction of intramolecular excitations or excess electrons with autolocal breaking of the translational symmetry. These excitations are now known as "Davydov's solitons" (1978-1988).
