Alexander Belavin

Alexander "Sasha " Belawin Abramovich (Russian Александр Абрамович Белавин, scientific transcription Aleksandr Abramovich Belavin, English transliteration: Alexander Belavin; * 1942 ) is a Russian theoretical physicist.

Belawin made ​​his Diploma in physics at MW Terent'ev and worked from 1967 to 1970 his doctorate on the theory of weak interactions with I. Kobzarew at the Institute for Theoretical and Experimental Physics ( ITEP ) in Moscow. He is a professor at the Independent University of Moscow and scientist at the Landau Institute for Theoretical Physics.

Belawin led in 1975 with Alexander Polyakov, Albert S. Black and Tjupkin the instantons a vacuum solutions of classical Yang-Mills theories in Euclidean space-time, which can be interpreted as a tunneling solutions between topologically distinct vacua in the usual space-time. They are studied in theories of quark confinement, and that was the motive for the original discoverers. In the early 1980s he worked on integrable (that is exactly solvable ) two-dimensional relativistic theories studied classical and quantum R-matrices and led an elliptic R-matrices. With Vladimir Drinfeld, who from these and subsequent studies defined the concept of quantum group later, he coined the classical R-matrices. With Polyakov and Alexander Samolodtschikow he wrote in 1984 a fundamental work on conformal field theories.

In 2007 he received the Pomeranchuk Prize. In 2011 he was awarded with Samolodtschikow and the Polyakov - Lars Onsager Prize
