Victor Emery (physicist)

from Wikipedia, the free encyclopedia

Victor John Emery (born May 16, 1934 in Boston , Lincolnshire , † July 17, 2002 in Wading Riber , New York ) was a British theoretical solid-state physicist.

Life

Emery studied at the University of London (Bachelor in Mathematics 1954) and received his PhD in theoretical nuclear physics from Manchester University with Richard Eden in 1957 . As a post-doc he was at Cambridge University (Cavendish Laboratory), at the Harwell nuclear research facility (AERE, Atomic Energy Research Establishment) and in 1959/60 at the University of California, Berkeley with Andrew Sessler as a Harkness Fellow. From 1960 he was a lecturer in Birmingham and 1963/64 Visiting Assistant Professor in Berkeley.

From 1964 he was at Brookhaven National Laboratory , where he had a permanent position since 1966 and was Senior Scientist from 1972, headed the low-temperature group from 1973 to 1977 and the solid-state theory group from 1975 to 1984 and from 1994. In 1984/85 he was scientific director of the HFBR (High Flux Beam Reactor). In 1971/72 he was visiting scholar at Nordita and in 1976 and 1981 visiting professor at Paris-Süd University in Orsay. From 1983 to 1987 he was Kramer's Lecturer at the University of Utrecht and also visiting professor at the Stevens Institute of Technology at the University of Sussex and McMaster University.

He died in 2002 of amyotrophic lateral sclerosis (ALS).

Emery dealt with quantum mechanical many-body theory, especially in solid-state physics. In Berkeley he worked on helium-3 quantum fluids, predicting pairing of fermionic atoms and superfluidity by analogy with the BCS theory of superconductivity (discovered by Douglas Osheroff , David M. Lee , Robert Coleman Richardson 1972). With Martin Blume and Robert Griffiths he developed a model of the phase separation in helium-3 / helium-4 mixtures. From 1970 he investigated strongly correlated electron systems and found with Alan Luther ; exact solutions for one-dimensional electron gas models (Emery-Luther-Fluid) and the phenomenon of the separation of charge and spin in the fundamental excitations. He also dealt with the Kondo problem . In the 1980s and 1990s he also investigated the high-temperature superconductors (HTSC) discovered in 1986 , partly with Steven Kivelson . He realized that the charge carriers are holes in the oxygen content of the copper oxide levels instead of in the copper, as was often assumed at the time. With Kivelson he developed a theory of HTSL, in which he also applied his experience with the one-dimensional case of strongly correlated electronic systems, with a separation of the dynamics of spin and charge, only that, according to his theory, in the two-dimensional case of HTSL due to the repulsion tendency of the doped hole charges in the spin structure of the underlying antiferromagnet form strips.

He was a member of the American Academy of Arts and Sciences (2001) and received the Oliver E. Buckley Condensed Matter Prize in 2001 for fundamental contributions to the theory of interacting electrons in one dimension .
