Viktor Nikolaevich Popov

from Wikipedia, the free encyclopedia

Viktor Nikolaevich Popov ( Russian Ви́ктор Никола́евич Попо́в , English transcription Victor Nikolaevich Popov; * October 27, 1937 , † April 16, 1994 ) was a Russian theoretical physicist.

Popov studied theoretical physics at the Leningrad State University (LGU) and from 1959 worked in J. Novoshilov's group at the Leningrad branch of the Steklov Institute (LOMI). After the group broke up, he went back to Leningrad University, where he completed his habilitation and became an assistant professor of mathematical physics. This is where the collaboration with his colleague Ludwig Faddejew began , initially through applications of the diagram techniques of quantum field theory in solid-state physics. In 1965 he went back to LOMI, where he stayed for the rest of his career and formed the group for mathematical physics with Faddejew.

He is known for his work on the quantization of gauge field theories , particularly the introduction of Faddejew-Popow ghosts with Ludwig Faddejew. Richard Feynman recognized the necessity of introducing such unphysical degrees of freedom in the quantization of gauge field theories in the early 1960s. Like Feynman, Faddejew and Popow initially examined Yang-Mills fields only as models of the quantization of gravity. Behind the Faddejew-Popow construction is the differential geometric interpretation of calibration fields with the help of fiber bundles , which Faddejew knew from the textbooks of André Lichnerowicz .
