Within the framework of relativistic quantum field theory, a novel method is established which allows for distinguishing non-equilibrium states admitting locally a thermodynamic interpretation. The basic idea is to compare these states with global equilibrium states (KMS states) by means of local th
It is shown that in a quantum field theory describing free, scalar particles with masses m,, i ~ ~q there exist locally normal equilibrium states with finite energy density for all temperatures fl > 0 if and only if Z ~ 1 e-~' < o0. This result lends support to the conjecture that the nuclearity cri
