Cosmological black holes from self-gravitating fields
Elcio Abdalla, Niayesh Afshordi, Michele Fontanini +2
Both cosmological expansion and black holes are ubiquitous features of our observable Universe, yet exact solutions connecting the two have remained elusive. To this end, we study…
Horizon instability of massless scalar perturbations of an extreme Reissner-Nordström-AdS black hole
Shao-Jun Zhang, Qiyuan Pan, Bin Wang +1
We study the stability of extreme Reissner-Nordström-AdS black hole under massless scalar perturbations. We show that the perturbation on the horizon of the extreme Reissner-Nordst…
Superradiant instability of extremal brane-world Reissner-Nordström black holes to charged scalar perturbations
Shao-Jun Zhang, Bin Wang, Elcio Abdalla
We examine the stability of extremal braneworld Reissner-Nordström black holes under massive charged scalar perturbations. We show that similar to the four-dimensional case, the su…
Separating expansion and collapse in general fluid models with heat flux
Morgan Le Delliou, José Pedro Mimoso, Filipe C. Mena +3
In this paper we consider spherically symmetric general fluids with heat flux, motivated by causal thermodynamics, and give the appropriate set of conditions that define separating…
The fermionic model
Elcio Abdalla, Antonio Lima-Santos
We consider the integrable model. As it turns out, relying on well known arguments, we claim that the conformally invariant fermionic model is solvable, the resulti…
The AdS/CFT relation, quasi-normal modes and applications
E. Abdalla, C. E. Pellicer, Jeferson de Oliveira
Here we present a fast review of some of developments and new results concerning applications of gravity in the context of the AdS/CFT correspondence, in brane world perturbations…
