On the (in)consistency of perturbation theory at finite temperature
Abstract A well-known difficulty of perturbative approaches to quantum field theory at finite temperature is the necessity to address theoretical constraints that are not present in the vacuum theory. In this work, we use lattice simulations of scalar correlation functions in massive ϕ 4 theory to a...
