Victor Emery
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 London University (Bachelor in Mathematics 1954) and in 1957 his PhD at Manchester University by Richard Eden in theoretical nuclear physics. As a post-doc, he was at the University of Cambridge ( Cavendish Laboratory ), at the Nuclear Research Centre Harwell ( AERE, Atomic Energy Research Establishment) and 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 at Berkeley.
Since 1964 he worked at the Brookhaven National Laboratory, where he had a full-time position since 1966 and from 1972 Senior Scientist, was the low-temperature group from 1973 to 1977 and the condensed matter theory group headed from 1975 to 1984 and from 1994. 1984/85 he was scientific director of the HFBR (High Flux Beam Reactor). 1971/72 he was a visiting scientist at the NORDITA as well as 1976 and 1981 Visiting Professor at the University of Paris-Sud in Orsay. From 1983 to 1987 he was Kramers Lecturer at Utrecht University and also a visiting professor at Stevens Institute of Technology, 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. At Berkeley, he studied with helium -3- quantum liquids, said he, in analogy to the BCS theory of superconductivity pairing of fermionic atoms and superfluidity predicted ( by Douglas Osheroff, David M. Lee, Robert Richardson discovered in 1972 ). With Martin Blume and Robert Griffiths, he developed a model of phase separation at Helium-3-/Helium-4-Mischungen. From 1970 he studied strongly correlated electron systems and found with Alan Luther; exact solutions for one-dimensional electron gas models ( Emery Luther liquid) and the phenomenon of separation of charge and spin in fundamental suggestions. He also dealt with the Kondo problem. In the 1980s and 1990s, he also examined the 1986 discovered high-temperature superconductors (HTSC ), some with Steven Kivelson. He realized that the charge carriers are holes at that period many cases in the oxygen content of the copper-oxide planes instead of copper. He developed by Kivelson a theory of HTSC in which he 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 the HTSC due to the repulsive tendency of form doped hole - charges in the spin structure of the underlying antiferromagnet strips.
He was a member of the American Academy of Arts and Sciences (2001) and received the 2001 Oliver E. Buckley Condensed Matter Prize for fundamental contributions to the theory of interacting electrons in one dimension.
