Gabriel Kotliar

from Wikipedia, the free encyclopedia

Gabriel Kotliar (born February 26, 1957 in Argentina ) is an American solid-state physicist.

Kotliar graduated from Hebrew University with a bachelor's degree in 1979 and a master's degree in 1980 and received his PhD from Princeton University in 1983 with Philip Warren Anderson . As a post-doctoral student , he was at the Institute of Theoretical Physics at the University of California, Santa Barbara until 1985 . In 1985 he became an Assistant Professor at the Massachusetts Institute of Technology and an Associate Professor in 1988 and Professor at Rutgers University in 1992 . There he is a Board of Governors Professor.

From 1991 to 1998 he was a consultant to Los Alamos National Laboratory and from 1988 to 1997 Bell Laboratories .

Building on the work of Dieter Vollhardt and Walter Metzner, he and Antoine Georges at Rutgers University developed the Dynamical Mean Field Theory (DMFT), a version of the molecular field theory for the treatment of strongly correlated electron systems. He researched Mott junctions , high temperature superconductors (HTS), the electronic structure of transition metal oxides, lanthanides and actinides and, in general, the development of ab initio methods for predicting the physical properties of materials (DMFT with extensions for example by including clusters, density functional theory, etc.). For example, he published on the electronic properties of plutonium including the prediction of the phonon spectrum and an early prediction of a d-wave component in high-temperature superconductors (with A. Ruckenstein). He researches the structure of HTS in iron pnictids and chalcogenides, which he considers to be a new class of strongly correlated electronic systems.

He also deals with disordered systems, for example in his dissertation in which he introduced a new spin-glass model, the influence of disorder (Anderson localization) in superconductors with impurities and in the modification of the Fermi fluid theory in the case of disorder. As a post-doctoral student, he worked on the growth of dendrites .

From 1986 to 1988 he was a Sloan Fellow, in 2003/04 he was a Guggenheim Fellow and in 1987 he received the Presidential Young Investigator Award from the National Science Foundation. In 2006 he and Dieter Vollhardt , Walter Metzner and Antoine Georges received the Agilent Technologies Europhysics Prize 2006 of the European Physical Society for the development of the Dynamical Mean Field Theory. For 2020, Kotliar and Georges were awarded the Aneesur Rahman Prize . In 1994/95 Kotliar was a Lady Davis Fellow at the Hebrew University. He was also visiting professor at the Ecole Polytechnique and the École normal supérieure in Paris. In 2005 he was Blaise Pascal visiting professor.

In 1996/97 he was Associate Editor of Physical Review Letters. In 2001 he became a Fellow of the American Physical Society and in 2019 a member of the National Academy of Sciences
