Gravitationally induced adiabatic particle production: From Big Bang to de Sitter
Jaume de Haro, Supriya Pan
In the background of a flat homogeneous and isotropic space-time, we consider a scenario of the universe driven by the gravitationally induced `adiabatic' particle production with…
Bulk viscous quintessential inflation
Jaume Haro, Supriya Pan
The incorporation of bulk viscosity process to General Relativity leads to the appearance of nonsingular backgrounds that, at early and late times, depict an accelerated universe.…
Bouncing cosmologies in geometries with positively curved spatial sections
Jaume de Haro
Background boucing cosmologies in the framework of General Relativity, driven by a single scalar field filling the Universe, and with a quasi-matter domination period, i.e., depict…
Discrepancies between observational data and theoretical forecast in single field slow roll inflation
Jaume Amorós, Jaume de Haro
The PLANCK collaboration has determined values for the spectral parameters of the CMB radiation, namely the spectral index , its running , the running of the running $β_s…
Bounce Loop Quantum Cosmology Corrected Gauss-Bonnet Gravity
J. Haro, A. N. Makarenko, A. N. Myagky +2
We develop a Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified theories of gravity. Within the context of our forma…
On the meaning of Painlevé--Gullstrand synchronization
Xavier Jaén, Alfred Molina
Following on from two recent papers, here we examine the relationship between Newtonian gravitation and general relativity in more depth. This allows us to define a scalar potentia…
