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…
Entangled pairs in evaporating black holes without event horizons
Ivan Agullo, Paula Calizaya Cabrera, Beatriz Elizaga Navascués
Investigations into Hawking radiation often assume a black hole model featuring an event horizon, despite the growing consensus that such causal structures may not exist in nature.…
Reduction of primordial chaos by generic quantum effects
Martin Bojowald, David Brizuela, Paula Calizaya Cabrera +1
According to general relativity, the generic early-universe dynamics is chaotic. Various quantum-gravity effects have been suggested that may change this behavior in different ways…
The chaotic behavior of the Bianchi IX model under the influence of quantum effects
Martin Bojowald, David Brizuela, Paula Calizaya Cabrera +1
A quantum analysis of the vacuum Bianchi IX model is performed, focusing in particular on the chaotic nature of the system. The framework constructed here is general enough for the…
Extended phase space thermodynamics for hairy black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We expand our results in \cite{Astefanesei:2019ehu} to investigate a general class of exact hairy black hole solutions in Einstein-Maxwell-dilaton gravity. The dilaton is endowed w…
Reentrant phase transitions in Einstein-Maxwell-scalar black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We consider how scalar fields affect the thermodynamic behavior of charged anti-de Sitter (AdS) black holes. We specifically investigate a class of (3+1)-dimensional exact hairy ch…
Family of dilatons and metrics for AdS/QCD models
Alfredo Vega, Paulina Cabrera
We explore some possibilities for obtaining useful metrics and dilatons for AdS/QCD models. As a guideline, we consider dilatons and/or metrics that on the one hand reproduce the m…
