James Burkett Hartle (born August 20, 1939 in Baltimore ) is an American theoretical physicist who deals with the fundamentals of quantum mechanics and cosmology.

Life

Hartle studied at Princeton University (Bachelor 1960) and received his doctorate in 1964 with the thesis Complex Angular Momentum in Three-Particle Potential Scattering with Murray Gell-Mann at Caltech . In 1963/64 he was at the Institute for Advanced Study . From 1964 he was an instructor at Princeton University and from 1966 first assistant professor and from 1972 professor at the University of California, Santa Barbara . In 1970 he received a research grant from the Alfred P. Sloan Foundation ( Sloan Research Fellowship ). From 1995 to 1997 he was director of the Institute for Theoretical Physics there and has retired (since 2012). 1981 to 1983 he was also a professor at the University of Chicago . Among other things, he was visiting professor at Cambridge ( Isaac Newton Institute and Gonville and Caius College 1994).

Hartle is one of the founders (with Robert Griffiths , Roland Omnès , Murray Gell-Mann) of the consistent histories interpretation of quantum mechanics using the ideas of decoherence . With Stephen Hawking author is of no boundary proposal for the quantum mechanical description of the universe.

From 1986 to 1995 he was a member of the International Committee of General Relativity and Gravitation. In 2009 he received the Einstein Prize of the American Physical Society . He has been a member of the National Academy of Sciences since 1991 , the American Academy of Arts and Sciences since 1989, and was elected a member of the American Philosophical Society in 2016.
