Barry Malcolm McCoy (born 14 December 1940 in Trenton, New Jersey) is an American physicist, known for his contributions to classical statistical mechanics, integrable models and conformal field theories.
He earned a B.Sc.
from California Institute of Technology (1963),
and a Ph.D.
With colleagues Tai Tsun Wu and Alexander Zamolodchikov, he was awarded the Dannie Heineman Prize for Mathematical Physics 1999, for "his work on the statistical mechanics of the Ising model,
including boundary critical phenomena, randomly layered systems which have Griffiths-McCoy singularities,
the Painleve representation of the two point function, quadratic difference equations for the n-point functions,
and the Ising model in a magnetic field.
Dr.
McCoy has in addition made contributions to the study of quantum spin chains, and the Fermionic representations of conformal field theory, and has been a co-discoverer of the integrable chiral Potts model.
He has also worked extensively in quantum field theory and more recently has become known for his mathematical work in nonlinear differential equations and the theory of Rogers-Ramanujan identities".His doctoral students include Rinat Kedem, Anne Schilling, and Craig Tracy.
