Paul Wiegmann

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

Wiegmann received his diploma in 1975 from the Moscow Institute of Physics and Technology in 1978 and his doctorate at the Landau Institute in Moscow with Anatoly Ivanovich Larkin. After that, he conducted research at the Landau Institute. From 1992 he was a professor in Chicago, where he became director of the James Franck Institute. He is there, Robert W. Reneker Distinguished Service Professor.

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

It also deals with non-linear physics and developed a theory of singularities in driven nonequilibrium systems ( classical and quantum mechanical).

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

In 2002 he 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-Sud.
