Optimized Perturbation Methods for the Free Energy of the Anharmonic Oscillator

High Energy Physics - Theory 2009-10-22 v1

Abstract

Two possibile applications of the optimized expansion for the free energy of the quantum-mechanical anharmonic oscillator are discussed. The first method is for the finite temperature effective potential; the second one, for the classical effective potential. The results of both methods show a quick convergence and agree well with the exact free energy in the whole range of temperatures.
