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 ...
The Mimetic Born-Infeld Gravity: The Primordial Cosmos and Spherically Symmetric Solutions
(MDPI, 2017-11-27)
The Eddington-inspired-Born-Infeld (EiBI) model is reformulated within the mimetic approach. In the presence of a mimetic field, the model contains non-trivial vacuum solutions. We study a realistic primordial vacuum ...
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 ...
