Alexei Lvovich Efros

from Wikipedia, the free encyclopedia

Alexei Lwowitsch Efros ( Russian Алексей Львович Эфрос ; born August 11, 1938 in Leningrad ) is a Russian-American theoretical solid-state physicist .

Efros studied at the Leningrad State Technical University with a diploma in 1961. From 1961 he was a scientist at the Joffe Institute in Leningrad (from 1985 as a senior scientist). In 1962 he received his doctorate there (on the quantum theory of conductivity in strong magnetic fields ) and habilitated in 1972 (Russian doctorate) with the thesis on the theory of heavily doped semiconductors . 1985 to 1989 he was also a professor at the Leningrad Electrotechnical Institute . From 1989 to 1991 he was visiting professor at the University of California, Riverside and from 1991 professor at the University of Utah . He has been a Distinguished Professor there since 1994 .

He deals with electron-electron interaction and transport theory in disordered semiconductor systems, including the theory of hopping conductivity (see band theory ). Efros and Boris Schklowski found a Coulomb gap at the Fermi energy in the single-particle density of states of electrons in localized states due to the Coulomb interaction with each other and said that it could be observed at low temperatures by reducing the conductivity compared to the theory of Nevill Mott ( Mott variable range hopping ) ahead ( Efros Shklovskii variable range hopping ). Their theory has been confirmed experimentally.

In 1986 he received the Landau Prize with Efros . In 1997 he received a Humboldt Research Award . He has been a Fellow of the American Physical Society since 1992 , which awarded him its Oliver E. Buckley Condensed Matter Prize for 2019 .

He is a US citizen. He has been married since 1994 and has two sons.

From 1987 to 1989 he was co-editor of Soviet Physics-Solid State and 1987 to 2000 of Solid State Communications .

He should not be confused with the solid-state physicist Alexander Efros or the computer scientist Alexei A. Efros .
