The Feynman effective classical potential in the Schrödinger formulation
arXiv:cond-mat/9906319 · doi:10.1103/PhysRevLett.81.3303
Abstract
New physical insight into the correspondence between path integral concepts and the Schrödinger formulation is gained by the analysis of the effective classical potential, that is defined within the Feynman path integral formulation of statistical mechanics. This potential is related to the quasi-static response of the equilibrium system to an external force. These findings allow for a comprehensive formulation of dynamical approximations based on this potential.
