John R. Klauder

John R. Klauder ( born January 24, 1932 in Reading, Pennsylvania) is an American theoretical physicist.

Life and work

Klauder studied at the University of Berkeley, at Stevens Institute of Technology and Princeton University, where he in 1957 made ​​his master's degree and in 1959 received his doctorate under John Archibald Wheeler. 1953 to 1988 he was a member of the Bell Labs in Murray Hill, New Jersey, where he was Head of the Department of Theoretical Physics and Solid State Spectroscopy Laboratory in the 1960s. Klauder was a visiting professor at Syracuse University (1967 /68), Rutgers University ( 1965), and at the University of Texas ( 1982), Bryn Mawr College, at Gakushuin University in Tokyo, in Oslo, at the IHES, the University of Paris the University of Bern (1961 /62, 1980, 1996). Since 1988 he is professor of physics and mathematics at the University of Florida in Gainesville. In 1986, he was in Princeton at the Institute for Advanced Study.

Klauders best-known works are the introduction of continuous representations in quantum mechanics (Journal of Mathematical Physics from 1963 to 1965 ) and 1960 and 1963, Coherent states for example in quantum optics. This happened before and independently of Roy Glauber, who gave them the name. He also deals with alternative quantization methods, in particular path integrals and quantization of gravity.

Klauder was the editor of the Journal of Mathematical Physics and President of the International Association of Mathematical Physics. In 2006 he was awarded the Lars Onsager - medal in Oslo.

Henry Leutwyler is one of his students.
