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 () ₂ model satisfies the relativistic KMS condition. Here we extend this result to general n-point functions.
Jakel et al. (Mon,) studied this question.
