# Alexander Solomonovich Kompaneyets

Alexander Solomonovich Kompaneyets (Russian: Александр Соломонович Компанеец) was born on January 4, 1914, in Ekaterinoslav, Russian Empire (now Dnipro, Ukraine) and died on August 19, 1974, in Palanga, Lithuania. He was a prominent physicist, author of a number of textbooks, and collaborator on the Soviet atomic bomb project who lived mainly in Moscow.

## Life

Kompaneyets was a student of Lev Landau in Kharkiv in the 1930s, where he dealt with solid state physics (electrical conductivity in metals and semiconductors). In 1936 he received his doctorate (candidate title) and habilitated in 1939 (Russian doctorate). He was a professor at the Institute of Chemical Physics at the Russian Academy of Sciences in Moscow (where he worked from 1946 until the end of his life) and is best known for his introductory textbook on theoretical physics. He also dealt with the physics of detonation, which he wrote about in a book with Yakov Zeldovich, and generally about gases at high temperatures.

In 1956, he published a work on the movement of charged particles (electrons) in intense radiation fields (Fokker–Planck equation with inverse Compton scattering (Comptonization), Kompaneyets' equation), which had arisen from secret work in the Soviet atomic bomb project and became important in the 1960s in works by Zeldovich and Rashid Sunyaev on the coupling of radiation and matter in the early universe (see also Sunyaev–Zeldovich effect). In the nuclear weapons program, he worked among others, Zeldovich since the 1940s (at the Institute of Chemical Physics), even at the theoretical examination (from 1948) of the early proposals (1946) of Zeldovich, Isaak Gurevich, Isaac Jakovlevic Pomeranchuk and Yulii Khariton on the hydrogen bomb. Kompaneyets dealt with many areas of theoretical physics, from chemical kinetics to biophysics.
