Semiclassical probability distribution function for finite-temperature field theory
Journal Article

· Phys. Rev., D; (United States)
Semiclassical methods for evaluating the canonical probability distribution function rho(phi) = in field theory for systems in thermodynamic equilibrium is studied. Field configurations which dominate the semiclassical distribution function are interpretable as finite-temperature most-probable escape paths (FTMPEP's) in field space and are related to the recently discovered caloron solutions, which are known to partially dominate the semiclassical partition function Z = ..integral..Dphi rho(phi). Presented is a semiclassical path-integral approximation for the distribution function and also discuss a Hartree self-consistent field approximation.
