Thin-shell wormholes in Rastall gravity
Iarley P. Lobo, Martin G. Richarte, J. P. Morais Graça +1
We constructed thin-shell wormholes using the well-known "cut and paste" technique for static black holes sourced by an anisotropic fluid within the context of the Rastall gravity.…
Effects of quantum corrections on the criticality and efficiency of black holes surrounded by a perfect fluid
V. B. Bezerra, I. P. Lobo, J. P. Morais Graça +1
We study some properties of the extended phase space of a quantum-corrected Schwarzschild black hole surrounded by a perfect fluid. In particular we demonstrate that, due to the qu…
Effects of a string cloud on the criticality and efficiency of AdS black holes as heat engines
J. P. Morais Graça, Iarley P. Lobo, Valdir B. Bezerra +1
We study the black hole thermodynamics in the presence of a string cloud matter distribution, considering a work term due to a variable cosmological "constant" in arbitrary dimensi…
Generalized entropy formalism and a new holographic dark energy model
A. Sayahian Jahromi, S. A. Moosavi, H. Moradpour +4
Recently, the Rényi and Tsallis generalized entropies have extensively been used in order to study various cosmological and gravitational setups. Here, using a special type of gene…
Relativistic Bose--Einstein condensates thin-shell wormholes
M. G. Richarte, I. G. Salako, J. P. Morais Graça +2
We construct traversable thin-shell wormholes which are asymptotically Ads/dS applying the cut and paste procedure for the case of an acoustic metric created by a relativistic Bose…
Scalar resonant frequencies and Hawking effect of an global monopole
H. S. Vieira, J. P. Morais Graça, V. B. Bezerra
Massive scalar fields are considered in the gravitational field produced by a Schwarzschild black hole with a global monopole in gravity. The exact solution of the radial pa…
