Allen Goldman
Allen Marshall Goldman (born October 18, 1937 in the Bronx , New York City ) is an American experimental solid-state physicist who specializes in superconductors .
Goldman attended Bronx High School of Science and studied physics and chemistry from Harvard University with a bachelor's degree (AB) in 1958 and a PhD in physics from Stanford University in 1965 . In the same year he became Assistant Professor and 1975 Professor at the University of Minnesota at Minneapolis, where he became an Institute of Technology Distinguished Professor in 1992 and headed the School of Physics and Astronomy from 1996 to 2009. In 2008 he became Regent's professor .
He is experimentally concerned with superconductors and the properties of electron transport in them, and in particular with superconducting thin films (two-dimensional systems). In the 1970s he later discovered collective excitations named after him in thin superconducting films (Carlson-Goldman modes, coupled collective excitations of the superconducting part (Cooper pairs) and the normal quasiparticles). He was one of the pioneers in studying phase transitions in two-dimensional systems, including the Kosterlitz-Thouless transition in thin superconducting films and networks of Josephson junctions . In the mid-1980s, he and his group developed a new method of producing extremely thin superconducting films and used it to investigate the phase transition from superconductor to insulator in thin films, which became a prime example of a quantum phase transition.
He investigated high temperature superconductors (HTS), magnetic superconductors, effects of disorder (and localization as a result) and superconducting nanowires. At HTS he was involved in the development of methods for their production with molecular beam epitaxy , which is an essential prerequisite for controlled meaningful experiments with HTS (exclusion of "dirt effects").
He is also concerned with magnetic oxides, materials with heavy fermions, topological phase transitions and the electrostatic modification of novel materials.
In 2015 he received the Oliver E. Buckley Condensed Matter Prize with Aharon Kapitulnik and Arthur Hebard and Matthew PA Fisher for the investigation of the phase transition superconductor-insulator as a paradigm of a quantum phase transition (laudation). In 2002 he received the Fritz London Memorial Prize . He headed the Condensed Matter Physics section of the APS.
He is a Fellow of the American Physical Society (1982) and the American Association for the Advancement of Science (1984) and a member of the National Academy of Sciences (2007). From 1966 to 1970 he was a Sloan Research Fellow .
From 1999 to 2005 he was Associate Editor of the Reviews of Modern Physics .
