Abstract

The infinite volume limit of the thermodynamic functions of an ideal Bose gas with respect to a grand-canonical equilibrium is taken such that the mean energy density is fixed. Above the critical mean energy density the macroscopically occupied ground state contributes to the mean entropy density while the mean density of the particle number has an infrared divergence. A thermodynamic stability result is derived; for a photon gas it means that, if condensation can be achieved, the condensed state should persist in the presence of a black perturbation.
