On the Population Distribution in a Photon Gas Near Zero Absolute Temperature
M.A. Grado-Caffaro and M. Grado-Caffaro
Considering realistically that the photon is an ultrarelativistic particle of non-zero rest-mass, we find the population distribution in a photon gas near null absolute temperature. In fact, we calculate this distribution as a function of the photon velocity and wavelength. In turn, the photon velocity depends on wavelength.
