Alexander Polyakov
From Wikipedia, the free encyclopedia
Alexander M. Polyakov is a physicist, formerly at the Landau Institute in Moscow, currently at Princeton University.
He is known for a number of basic contributions to quantum field theory, including work on what is now called the 't Hooft-Polyakov monopole in non-abelian gauge theory, independent from Gerard 't Hooft. His paper Infinite conformal symmetry in two-dimensional quantum field theory, with A. A. Belavin, and A.B. Zamolodchikov, from 1984, has classic status. His path integral formulation of string theory had profound and lasting impacts in the conceptual and mathematical understanding of the theory.
He was awarded the Dirac Medal in 1986, and the Lorentz Medal in 1994.
