Fundamental theories in a phantom universe
Pedro F. Gonzalez-Diaz
Starting with the holographic dark energy model of Li it is shown that the holographic screen at the future event horizon is sent toward infinity in the phantom energy case, so all…
On tachyon and sub-quantum phantom cosmologies
Pedro F. Gonzalez-Diaz
This paper deals with dark and phantom energy in the tachyon and sub-quantum models for dark energy. We obtain that the simplest condition for such a regime to occur in these scena…
Dark energy and supermassive black holes
Pedro F. Gonzalez-Diaz
This paper deals with a cosmological model in which the universe is filled with tachyon dark energy in order to describe current and future accelerating expansion. We obtain that t…
Phantom thermodynamics
Pedro F. Gonzalez-Diaz, Carmen L. Siguenza
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 genera…
Phantom inflation and the "Big Trip"
Pedro F. Gonzalez-Diaz, Jose A. Jimenez-Madrid
Primordial inflation is regarded to be driven by a phantom field which is here implemented as a scalar field satisfying an equation of state , with . Being even aggrava…
Achronal cosmic future
Pedro F. Gonzalez-Diaz
The spherically symmetric accretion of dark and phantom energy onto Morris-Thorne wormholes is considered. It is obtained that the accretion of phantom energy leads to a gradual in…
