Insight into the microscopic structure of an AdS black hole from a thermodynamical phase transition.
Comparing with an ordinary thermodynamic system, we investigate the possible microscopic structure of a charged anti-de Sitter black hole completely from the thermodynamic viewpoint. The number… Expand
Repulsive Interactions and Universal Properties of Charged Anti-de Sitter Black Hole Microstructures.
The Ruppeiner geometry of thermodynamic fluctuations provides a powerful diagnostic of black hole microstructures. We investigate this for charged anti-de Sitter black holes and find that, while an… Expand
Ruppeiner Geometry, Phase Transitions, and the Microstructure of Charged AdS Black Holes
We present a novel approach for probing the microstructure of a thermodynamic system that combines thermodynamic phase transitions with the Ruppeiner scalar curvature. Originally considered for van… Expand
Hidden conformal symmetry of the Kerr-Newman black hole
We investigate the hidden conformal symmetry of the 4-dimensional non-extremal Kerr-Newman (KN) black hole with the idea of the near-region Kerr/CFT correspondence proposed by Castro, Maloney and… Expand
Intriguing microstructures of five-dimensional neutral Gauss-Bonnet AdS black hole
Abstract In this paper, we analytically study the phase structure and construct the Ruppeiner geometry in the extended phase space for the five-dimensional neutral Gauss-Bonnet AdS black hole.… Expand
Black hole solution and strong gravitational lensing in Eddington-inspired Born–Infeld gravity
A new theory of gravity called Eddington-inspired Born–Infeld (EiBI) gravity was recently proposed by Bañados and Ferreira. This theory leads to some exciting new features, such as free of… Expand
Emergence of Cosmic Space and the Generalized Holographic Equipartition
Recently, a novel idea about our expanding Universe was proposed by T. Padmanabhan [arXiv:1206.4916]. He suggested that the expansion of our Universe can be thought of as the emergence of space as… Expand
Charged spinning black holes as particle accelerators
It has recently been pointed out that the spinning Kerr black hole with maximal spin could act as a particle collider with arbitrarily high center-of-mass energy. In this paper, we will extend the… Expand
Born-Infeld Black Holes in 4D Einstein-Gauss-Bonnet Gravity
A novel four-dimensional Einstein-Gauss-Bonnet gravity was formulated by D. Glavan and C. Lin [Phys. Rev. Lett. 124, 081301 (2020)], which is intended to bypass the Lovelock's theorem and to yield a… Expand
Linear perturbations in Eddington-inspired Born-Infeld gravity
We study the full linear perturbations of a homogeneous and isotropic spacetime in the Eddington-inspired Born-Infeld gravity. The stabilities of the perturbations are analyzed in the Eddington… Expand
