Dark energy as generalised superfluid excitations
Abstract
In this paper we present a generic form of the cosmological Equation of State derived from the formalism of Statistical Mechanics, assuming that a cosmic acceleration scenario can be interpreted as a system of quasi-particles. By considering a generalised superfluidity approach, in which the energy spectrum can be modulated via a parameter s, a negative equation of state arises as excitations associated with an exotic superfluid system. We show that for s 0.293, w-1, which can be related to the standard equation of state for the model.
