Thermodynamical properties of bosons and fermions for a lattice motivated dispersion relationship

Abstract

In this paper we calculate the basic thermodynamical quantities for a system of bosonic simple harmonic oscillators (BSHOs) and the corresponding system of fermionic simple harmonic oscillators (FSHOs) using a dispersion relationship similar to cases in general relativity and condensed matter physics. In the FSHO, we see negative temperatures, and in both cases we obtain finally a system of oscillators with only one effective frequency of vibration. Also we see that pressure is less than zero for T[Formula: see text][Formula: see text][Formula: see text]Tc where Tc is the critical temperature for bosons.
