Alexander M. Polyakov (born 27 September 1945) is a theoretical physicist, formerly at the Landau Institute in Moscow, currently at Princeton University.

Important discoveries

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.

He also played an important role in elucidating the conceptual framework behind renormalization independent of Kenneth Wilson's Nobel prize winning work. He formulated pioneering ideas in gauge/string duality long before the breakthrough of AdS/CFT using D-branes. Other insightful conjectures that came years or even decades before active work by others include integrability of gauge and string theories and certain ideas about turbulence.

Honors and Awards
