George Csanak from the Los Alamos National Laboratory (born 1941) is a Hungarian-born American physicist. He was awarded the status of Fellow in the American Physical Society, after they were nominated by their Division of Atomic, Molecular & Optical Physics in 1995, for development of many-body Green's function techniques of bound-state and scattering properties of atomic and molecular systems; significant contributions to the theoretical foundation and physical interpretation of electron-photon coincidence experiments, and for contributions to the understanding of electron scattering.
