K-Essential Phantom Energy: Doomsday around the corner?
Pedro F. Gonzalez-Diaz
In spite of its rather weird properties which include violation of the dominant-energy condition, the requirement of superluminal sound speed and increasing vacuum-energy density,…
Sub-Quantum Dark Energy
Pedro F. Gonzalez-Diaz
A procedure is considered which upgrades the Lagrangian description of quantum relativistic particles to the Lagrangian of a proper field theory in the case that the Klein-Gordon w…
Tensorial perturbations in the bulk of inflating brane worlds
Pedro F. Gonzalez-Diaz
In this paper we consider the stability of some inflating brane-world models in quantum cosmology. It is shown that whereas the singular model based on the construction of inflatin…
Wormholes and Ringholes in a Dark-Energy Universe
Pedro F. Gonzalez-Diaz
The effects that the present accelerating expansion of the universe has on the size and shape of Lorentzian wormholes and ringholes are considered. It is shown that, quite similarl…
You need not be afraid of phantom energy
Pedro F. Gonzalez-Diaz
Phantom energy which violates the dominant-energy condition and is not excluded by current constraints on the equation of state may be dominating the evolution of the universe now.…
