Phantom thermodynamics [PDF]

open access: yesNuclear Physics B, 2004
This paper deals with the thermodynamic properties of a phantom field in a flat Friedmann-Robertson-Walker universe. General expressions for the temperature and entropy of a general dark-energy field with equation of state $p=\omega\rho$ are derived from

Quantum de Sitter cosmology and phantom matter

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2003
We consider deSitter universe and Nariai universe induced by quantum CFT with classical phantom matter and perfect fluid. The model represents the combination of trace-anomaly driven inflation and phantom driven deSitter universe.
