Scalar field propagation in higher dimensional black holes at a Lifshitz point
Elcio Abdalla, Owen Pavel Fernández Piedra, Fidel Sosa Nuñez +1
We study the complete time evolution of scalar fields propagating in space-times of higher dimensional Lifshitz Black Holes with dynamical critical exponent , obtained from a…
Realistic fluids as source for dynamically accreting black holes in a cosmological background
Daniel C. Guariento, Michele Fontanini, Alan M. da Silva +1
We show that a single imperfect fluid can be used as a source to obtain the generalized McVittie metric as an exact solution to Einstein's equations. The mass parameter in this met…
A Model for Dark Energy decay
Elcio Abdalla, Leila Graef, Bin Wang
We discuss a model of non perturbative decay of dark energy into hot and cold dark matter. This model provides a mechanism from the field theory to realize the energy transfer from…
