Semiclassical Approximation for the Partition Function in QFT
In this paper we discuss the semiclassical approximation for the thermodynamics of scalar fields. We constructa semiclassical propagator in terms of two solutions of an ordinary differential equation. The main resultis an analytic (non-perturbative) expression for the partition function written in t...
