Barry Malcolm McCoy (born December 14, 1940 in Trenton , New Jersey ) is an American theoretical physicist .

McCoy received his Bachelor's degree from Caltech in 1963 and his PhD from Harvard in 1967 with Tai Tsun Wu ( Spin correlations of the two dimensional Ising model ). He then went to the State University of New York at Stony Brook , where he became an Assistant Professor in 1969 and is currently Professor (since 1979 Distinguished Professor of Physics). He was visiting professor in Kyoto , at the Australian National University in Canberra and at the Institute Henri Poincare in Paris. In 1973 he received a research grant from the Alfred P. Sloan Foundation ( Sloan Research Fellowship ).

McCoy worked on the Ising model (critical behavior at edges, behavior in a magnetic field, difference equations for its correlation functions), quantum spin chains and other integrable models of statistical mechanics. He is one of the co-discoverers of the chiral Potts model. He also dealt with quantum field theory, fermion representation of conformal field theories, nonlinear differential equations and Rogers-Ramanujan identities.

His discovery (1976, with Wu and others) that the correlation functions in the Ising model are solutions of nonlinear differential equations (of the Painlevé type), marked the beginning of similar investigations with other grid models in the 1980s.

In 1999 he received the Dannie Heineman Prize for Mathematical Physics . In 1998 he was invited speaker at the International Congress of Mathematicians in Berlin ( Rogers-Ramanujan identities: a century of progress from mathematics to physics with Alexander Berkovich).
