Quantum cosmology of the Big Rip: Within GR and in a modified theory of gravity
(MDPI, 2017-04-14)
Quantum gravity is the theory that is expected to successfully describe systems that are under strong gravitational effects while at the same time being of an extreme quantum nature. When this principle is applied to the ...
Cosmological Perturbations in Phantom Dark Energy Models
(MDPI, 2017-03-06)
The CDM paradigm, characterised by a constant equation of state w = -1 for dark energy, is the model that better fits observations. However, the same observations strongly support the possibility of a dark energy content ...
Doomsdays in a modified theory of gravity: a classical and a quantum approach
(Elsevier, 2017-09-10)
By far cosmology is one of the most exciting subject to study, even more so with the current bulk of observations we have at hand. These observations might indicate different kinds of doomsdays, if dark energy follows ...
