Effective Regge-Wheeler equations of a hybrid loop quantum black hole
Beatriz Elizaga Navascués, Alvaro Torres-Caballeros
A set of effective equations for the gauge-invariant gravitational perturbations in the interior of a spherically symmetric, non-rotating black hole is derived within the framework…

Vacuum-purified Hawking radiation from evaporating black holes: Lessons from moving mirrors
Ivan Agullo, Paula Calizaya Cabrera, Beatriz Elizaga Navascués
This article investigates the possibility that Hawking-like quanta emitted by a moving mirror can be purified by late-time vacuum fluctuations, as proposed in Hotta, Schützhold and…

On the evolution of the volume in Loop Quantum Cosmology
Beatriz Elizaga Navascués
The dynamics of the expectation value of the volume is one of the key ingredients behind the replacement of the Big Bang singularity by a bounce in Loop Quantum Cosmology. As such,…
