Hawking radiation and black hole gravitational back reaction - A quantum geometrodynamical simplified model
João Marto
The purpose of this paper is to analyse the back reaction problem, between Hawking radiation and the black hole, in a simplified model for the black hole evaporation in the quantum…
A varying Dark Energy effective speed of sound parameter in the phantom Universe
Imanol Albarran, Mariam Bouhmadi-López, João Marto
We analyse the phenomenological effects of a varying Dark Energy (DE) effective speed of sound parameter, , on the cosmological perturbations of three phantom…
Inflaton candidates: from string theory to particle physics
K. Sravan Kumar
Cosmic inflation is the cornerstone of modern cosmology. In particular, following the Planck mission reports presented in 2015 regarding cosmic microwave background (CMB), there is…
Towards nonsingular rotating compact object in ghost-free infinite derivative gravity
Luca Buoninfante, Alan S. Cornell, Gerhard Harmsen +4
The vacuum solution of Einstein's theory of general relativity provides a rotating metric with a ring singularity, which is covered by the inner and outer horizons, and an ergo reg…
Conformally-flat, non-singular static metric in infinite derivative gravity
Luca Buoninfante, Alexey S. Koshelev, Gaetano Lambiase +2
In Einstein's theory of general relativity the vacuum solution yields a blackhole with a curvature singularity, where there exists a point-like source with a Dirac delta distributi…
Kinetic inflation in deformed phase space Brans-Dicke cosmology
S. M. M. Rasouli, J. Marto, P. V. Moniz
In this paper, by establishing a Brans-Dicke (BD) cosmology by means of a deformed phase space, in the absence of any scalar potential, cosmological constant and ordinary matter, w…
