Paper Abstract

In this paper, the density of modes in quantum cubic cavities is calculated taking into account the small number of modes. Then the `spatial quantization' fluctuations, which appear as a correction factor in the mode density, are introduced in the Planck law. The discrete form of the Planck radiation spectrum is demonstrated and the limits of this double-quantum regime of the cubic cavity are set for the product of cavity size by temperature. LT(epsilon) (0.1, 1). A reciprocity rule for the cavity size and the temperature is shown. Calculating the total energy in the quantum cubic cavities (QCC), we found out a `corrected' Stefan-Boltzmann law for the double-quantum regime. Furthermore, the corrections for all thermodynamic functions of the photon gas in QCC are given.
