Holographic cosmic energy, fundamental physics and the future of the universe
Pedro F. Gonzalez-Diaz
Holographic dark energy models have been recently suggested which most clearly show that accelerating cosmology appears to be incompatible with mathematically consistent formulatio…
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…
Accelerating universe without event horizon
Pedro F. Gonzalez-Diaz
It is shown that if a small negative cosmological constant is added to quintessence models with equation of state on the range , the resulting scenarios could n…
Can black holes exist in an accelerating universe?
Pedro F. Gonzalez-Diaz
This letter deals with an analysis of the space-time static metric that corresponds to a quintessential state equation with constant characteristic parameter. Following a procedure…
Perfect fluid brane-world model
M. Bouhmadi-Lopez, P. F. Gonzalez-Diaz, A. Zhuk
By considering 5--dimensional cosmological models with a bulk filled with a perfect fluid and a cosmological constant, we have found regular instantonic solution which is free from…
