چکیده
We find that the Kerr-(Newman)-AdS$_4$ black hole will be shadowless if its rotation parameter is larger than a critical value and shadowless-ness may related to appearance of null hypersurface caustics (NHC) both inside Cauchy horizon outside event for with beyond value. Our studies also further confirm whether an ultraspinning super-entropic or not unrelated existence NHC horizon.

Cardy-Verlinde Formula and Kerr-Newman-AdS4 and Kerr-Newman-dS4 black holes
The Cardy-Verlinde formula, which expresses the entropy of the conformal field theory in terms of its total energy (or the extensive energy), Casimir energy and radius of the unit sphere S, is further verified by using the KerrNewman-AdS4 and Kerr-Newman-dS4 black holes. For the Kerr-NewmanAdS4 black hole, we find that to cast the entropy of the conformal field theory into the Cardy-Verlinde fo...

متن کاملCardy-Verlinde Formula and entropy bounds in Kerr-Newman-AdS4/dS4 black holes backgrounds
The Cardy-Verlinde formula is further verified by using the Kerr-NewmanAdS4 and Kerr-Newman-dS4 black holes. In the Kerr-Newman-AdS4 spacetime, we find that, for strongly coupled CFTs with AdS duals, to cast the entropy of the CFT into the Cardy-Verlinde formula the Casimir energy must contains the terms −n ( JΩH + QΦ 2 + QΦ0 2 ) , which associate with rotational and electric potential energies...
متن کاملThermodynamic curvature and phase transitions in Kerr-Newman black holes
Singularities in the thermodynamics of Kerr-Newman black holes are commonly associated with phase transitions. However, such interpretations are complicated by a lack of stability and, more significantly, by a lack of conclusive insight from microscopic models. Here, I focus on the later problem. I use the thermodynamic Riemannian curvature scalar R as a try to get microscopic information from ...

Marcelo Samuel Berman Editora Albert Einstein Ltda. R. Candido Hartman,575 #17 Ed. Renoir-Champagnat 80730-440 Curitiba PR BRAZIL ABSTRACT New formulae are obtained for the energy of K.N. b.h.’s that point out a gravitomagnetic energy effect. The results are valid for slowly or rapidly rotating black-holes. The expression of the energy density of Kerr-Newman back-holes in the slow rotation case...
