The relativistic KMS condition for the thermal n-point functions of the P(ϕ)_2 model

Abstract

Thermal quantum field theories are expected to obey a relativistic KMS condition, which replaces both the relativistic spectrum condition of Wightman quantum field theory and the KMS condition, which characterises equilibrium states in quantum statistical mechanics. In a previous work it has been shown that the two-point function of the thermal $P(\varphi {)}_2$ model satisfies the relativistic KMS condition. Here we extend this result to general $n$-point functions.
