Reheating in small-field inflation on the brane: The Swampland Criteria and observational constraints in light of the PLANCK 2018 results
Constanza Osses, Nelson Videla, Grigoris Panotopoulos
We study cosmological inflation and its dynamics in the framework of the Randall-Sundrum II brane model. In particular, we analyze in detail four representative small-field inflati…
Building (1+1) holographic superconductors in the presence of non-linear Electrodynamics
Grigoris Panotopoulos
In the framework of the gauge/gravity duality, and in particular of the correspondence, we study one-dimensional superconductors analyzing the dual (1+2)-dimensional…
Quasinormal modes of the BTZ black hole under scalar perturbations with a non-minimal coupling: Exact spectrum
Grigoris Panotopoulos
We perturb the non-rotating BTZ black hole with a non-minimally coupled massless scalar field, and we compute the quasinormal spectrum exactly. We solve the radial equation in term…
Greybody factors for a minimally coupled scalar field in three-dimensional Einstein-power-Maxwell black hole background
Grigoris Panotopoulos, Angel Rincon
In the present work we study the propagation of a probe minimally coupled scalar field in Einstein-power-Maxwell charged black hole background in (1+2) dimensions. We find analytic…
Quasinormal modes of scale dependent black holes in (1+2)-dimensional Einstein-power-Maxwell theory
Angel Rincon, Grigoris Panotopoulos
We study for the first time the stability against scalar perturbations, and we compute the spectrum of quasinormal modes of three-dimensional charged black holes in Einstein-power-…
Quasinormal modes of black holes in Einstein-power-Maxwell theory
Grigoris Panotopoulos, Angel Rincon
In the present work we compute the spectrum of quasinormal frequencies of four-dimensional charged black holes in Einstein-power-Maxwell theory. In particular we study scalar pertu…
