Spectrum of $\gamma$-Fluids: A Statistical Derivation

High Energy Physics - Theory 2007-05-23 v1

Abstract

The spectrum of massless bosonic and fermionic fluids satisfying the equation of state p=(γ1)ρp=(\gamma-1)\rho is derived using elementary statistical methods. As a limiting case, the Lorentz invariant spectrum of the vacuum (γ=0,p=ρ\gamma=0, p=-\rho) is deduced. These results are in agreement with our earlier derivation for bosons using thermodynamics and semiclassical considerations.
