Mimicking wormholes in Born-Infeld electrodynamics
Jose Beltrán Jiménez, Luis J. Garay, María Pérez Garrote
We compute the evolution of linear perturbations on top of a background solution of a general nonlinear electromagnetic theory. This evolution can be described in terms of two effe…
No-hair and almost-no-hair results for static axisymmetric black holes and ultracompact objects in astrophysical environments
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay +1
No-hair theorems are uniqueness results constraining the form of the metric of black holes in general relativity. These theorems are typically formulated under idealized assumption…
From loop quantum gravity to cosmology: the two-vertex model
Álvaro Cendal, Iñaki Garay, Luis J. Garay
We study the notion of volume and its dynamics in the loop-quantum-gravity truncation known as the two-vertex model. We also show that its U(N)-symmetry reduction provides the old…
Adiabatic approach to the trans-Planckian problem in Loop Quantum Cosmology
Luis J. Garay, Mario López González, Mercedes Martín-Benito +1
We study the scalar modes that, being observable today, were trans-Planckian before inflation, within the context of hybrid Loop Quantum Cosmology (LQC). We analyse the dynamics of…
