Alexander Borissowitsch Zamolodchikov (Russian: Алекса́ндр Бори́сович Замоло́дчиков; born September 18, 1952) is a Russian physicist, known for his contributions to condensed matter physics and string theory.
Born in Novo-Ivankovo, now part of Dubna, he earned a M.Sc. in nuclear engineering (1975) from Moscow Institute of Physics and Technology, a Ph.D. in physics from the Institute for Theoretical and Experimental Physics (1978). He joined the research staff of Landau Institute for Theoretical Physics (1978) where he got an honorary doctorate (1983). He co-authored the famous paper Infinite conformal symmetry in two-dimensional quantum field theory, with Alexander Polyakov and Alexander Belavin.
- 1999 Dannie Heineman Prize for Mathematical Physics with Barry M. McCoy and Tai Tsun Wu for "their groundbreaking and penetrating work on classical statistical mechanics, integrable models and conformal field theories."
