Paul Wiegmann

from Wikipedia, the free encyclopedia

Paul B. Wiegmann ( Russian Павел Борисович Вигман , Pawel Borissowitsch Wiegman ; born November 8, 1952 in Ryazan ) is a Russian-American theoretical physicist who is a professor at the James Franck Institute at the University of Chicago .

Wiegmann received his diploma from the Moscow Institute for Physics and Technology in 1975 and received his doctorate in 1978 from the Landau Institute in Moscow under Anatoly Ivanovich Larkin . Then he did research at the Landau Institute. From 1992 he was a professor in Chicago, where he became director of the James Franck Institute. There he is Robert W. Reneker Distinguished Service Professor .

Before joining Chicago, he worked at the Institute for Advanced Study .

He also deals with nonlinear physics and developed a theory of singularities in driven non-equilibrium systems (classical and quantum mechanical).

Wiegmann was able to find exact solutions for a number of models of interacting electrons in solid state physics and in quantum field theory, for example for the nonlinear sigma model in two dimensions with symmetry group O (3), for the Kondo problem (with the Bethe Approach , independent Natan Andrei ), for the Anderson model of magnetic impurities and for the Wess-Zumino-Witten model (with Alexander Poljakow ). In particular, he was one of the pioneers in the application of topological methods in theoretical solid-state physics and emphasized their role in quantum mechanical many-body physics.

In 2002 Wiegmann received the Humboldt Research Award . In 2003 he became a Fellow of the American Physical Society . In 2004 he was Kramers Professor at the University of Utrecht (Spinoza Institute) and in 2006 he held the Blaise Pascal Chair at the University of Paris-South . For 2017, Wiegmann was awarded the Lars Onsager Prize together with Natan Andrei .
