Abstract

Thermodynamic properties of dark energy are discussed assuming that dark energy is described in terms of a selfinteracting complex scalar. We first show that, under certain assumptions, selfinteracting complex scalar field theories are equivalent to purely kinetic k‐essence models. Then we analazie the themal properties of k‐essence and in particular we show that dark‐energy in the phantom regime does not necesserely yield negative entropy.
