Bouncing cosmologies via modified gravity in the ADM formalism: Application to Loop Quantum Cosmology
Jaume de Haro, Jaume Amorós
We consider the ADM formalism as a tool to build bouncing cosmologies. In this approach, the foliation of the spacetime has to be fixed in order to go beyond General Relativity mod…
Reheating via gravitational particle production in simple models of quintessence or CDM inflation
Jaume Haro, Llibert Aresté Saló
We have tested some simple CDM (the same test is also valid for quintessence) inflation models, imposing that they match with the recent observational data provided by the BICEP…
Quintessential inflation at low reheating temperatures
Llibert Aresté Saló, Jaume de Haro
We have tested some simple quintessential inflation models, imposing that they match with the recent observational data provided by the BICEP and Planck's team and leading to a reh…
Viscous Cosmology for Early- and Late-Time Universe
Iver Brevik, Øyvind Grøn, Jaume de Haro +2
From a hydrodynamicist's point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all a…
Non-Singular Black Holes, the Cosmological Constant and Asymptotic Safety
Ramon Torres
Quantum gravitational effects in black hole spacetimes with a cosmological constant are considered. The effective quantum spacetimes for the black holes are constructed by taki…
The matter-ekpyrotic bounce scenario in Loop Quantum Cosmology
Jaume Haro, Jaume Amorós, Llibert Aresté Saló
We will perform a detailed study of the matter-ekpyrotic bouncing scenario in Loop Quantum Cosmology using the methods of the dynamical systems theory. We will show that when the b…
