William A. Bardeen
William Allan Bardeen ( born September 15, 1941 in Washington, Pennsylvania) is an American theoretical physicist.
Bardeen is the son of Nobel Prize winner John Bardeen. He studied at Cornell University ( completion 1962) and received his doctorate at the University of Minnesota in 1968. Then he was at the State University of New York at Stony Brook and in 1968 /9 on the Institute for Advanced Study in Princeton before he went to Stanford University as an Assistant and then Associate Professor. From 1975 he was at the Fermi National Accelerator Laboratory ( Fermilab ), where he headed the theoretical division. 1993/4 he was also head of the theoretical department of the proposed Superconducting Super Collider ( SSC ) before it was discontinued. He was, inter alia, as a visiting scientist at the Max Planck Institute for Physics and Astrophysics in Garching near Munich, at CERN, at the Tata Institute of Fundamental Research, at the University of Paris, the Institute of Theoretical Physics in Santa Barbara and at the Research Institute for Fundamental Physics in Kyoto.
Bardeen is mainly for his work on anomalies ( diagrams of the quantized theory, which break the symmetry of the corresponding classical theory ) in quantum field theory ( QFT ) is known. He is one of the discoverers of the axial vector anomaly of fermion currents, which he treated as a first also for non - Abelian gauge theories and proved for these anomalies with Stephen Adler, the absence of perturbative corrections ("No Renomalization Theorem" ), making it the fundamental nature of these anomalies aufzeigten that can not be made to disappear by graphs of higher order. He also made important contributions to the perturbative quantum chromodynamics and theories of dynamic fracture of the symmetry of the electroweak interactions of the Standard Model and examined theories with axions.
In 1985 he was Guggenheim Fellow and 1996 he received the Sakurai Prize. He was also a Sloan Fellow 1971 to 1974 and 1977, he received the Senior Scientist Award from the Alexander -von- Humboldt Foundation. He is a member of the American Academy of Arts and Sciences since 1999 and of the National Academy of Sciences. In 2002 he received an honorary doctorate from the University of Minnesota.
Bardeen is married and has two children. His brother James M. Bardeen Professor of Astrophysics at Washington University.
He has been married since 1961 and has a son and a daughter.
