Charles Behan Thorn III. (Born August 14, 1946 in Washington, Indiana ) is an American theoretical physicist .

Life

Thorn studied at the Massachusetts Institute of Technology with a bachelor's degree in 1968 and at the University of California, Berkeley , with a master's degree in 1969 and a doctorate in elementary particle theory in 1971 with Stanley Mandelstam with the work Aspects of dual resonance models . He was a post-doctoral student at CERN in 1972 . In 1973 he became an assistant professor and later an associate professor at MIT and in 1980 professor at the University of Florida at Gainesville.

In 1985 he was visiting professor at the Ecole Normale Superieure and in 1976 and 1991 visiting scholar at the Department of Applied Mathematics and Theoretical Physics (DAMTP) at Cambridge University .

In the 1970s, Thorn was one of the authors (with Victor Weisskopf , Kenneth A. Johnson , Robert L. Jaffe , Alan Chodos ) of the MIT Bag Model of Hadrons, a simplified model of hadrons as quarks trapped in a volume with perturbation-theoretical quantum chromodynamics residue -Interaction.

He is also known for contributions to string theory dating back to the 1970s (when these were known as dual models in strong interaction theory). With Peter Goddard , he proved the absence of negative norms (causality-violating ghost states) in boson string theory.

He is a fellow of the American Physical Society . In 1986/87 he was a Guggenheim Fellow and at the Institute for Advanced Study . In 1974 he was a Sloan Research Fellow .
