Tidal Response Beyond the Background Geometry in Einstein-Euler-Heisenberg Black Holes
Ramon Becar, P. A. Gonzalez, Ali Ovgun +2
We determine the quadrupolar logarithmic tidal response of electrically charged Einstein-Euler-Heisenberg black holes from the coupled static odd-parity gravitational and electroma…
Phase-space analysis of torsion-coupled dilatonic ghost condensate
Manuel Gonzalez-Espinoza, Giovanni Otalora, Yoelsy Leyva +1
We studied the cosmological dynamics of a dilatonic ghost condensate field as a source of dark energy, which is non-minimally coupled to gravity through torsion. We performed a det…
Dynamics of dark energy in a scalar-vector-torsion theory
Manuel Gonzalez-Espinoza, Giovanni Otalora, Yoelsy Leyva +1
We study the cosmological dynamics of dark energy in a scalar-vector-torsion theory. The vector field is described by the cosmic triad and the scalar field is of the quintessence t…
Quasinormal modes for massive charged scalar fields in Reissner-Nordström dS black holes: anomalous decay rate
P. A. González, Eleftherios Papantonopoulos, Joel Saavedra +1
The anomalous decay rate of the quasinormal modes occurs when the longest-lived modes are the ones with higher angular number. Such behaviour has been recently studied in different…
Quasinormal modes for a non-minimally coupled scalar field in a five-dimensional Einstein-power-Maxwell background
Angel Rincon, P. A. Gonzalez, Grigoris Panotopoulos +2
We study the propagation of massless scalar fields non-minimally coupled to gravity in the background of five-dimensional Einstein-power-Maxwell black holes, and using the WKB and…
Inflation and Primordial Fluctuations in Gravity's Rainbow
Yoelsy Leyva, Carlos Leiva, Giovanni Otalora +1
We study slow-roll inflation and the generation of primordial fluctuations in gravity's rainbow. We obtain the second order action for scalar and tensor perturbations and th…
