چکیده
Abstract Recently, two kinds of deformed schwarzschild spacetime have been proposed, which are the black-bounces metric (Simpson and Visser in J Cosmol Astropart Phys 2019:042, 2019, Lobo et al. Rev D 103:084052, 2021) quantum black hole (BH) (Berry arXiv:2102.02471 , 2021). In present work, we investigate rotating these Schwarzschild metric. They exact solutions to Einstein’s field equation. We analyzed properties spacetimes, such as event horizon (EH), stationary limit surface (SIS), structure singularity ring, energy condition (EC), etc., found that some novel properties.

Generalized Area Law under Multi-parameter Rotating Black Hole Spacetime
Abstract We study the statistical mechanics for quantum scalar fields under the multiparameter rotating black hole spacetime in arbitrary D dimensions. The method of analysis is general in the sense that the metric does not depend on the explicit black hole solutions. The generalized Stefan-Boltzmann’s law for the scalar field is derived by considering the allowed energy region properly. Then t...
متن کاملSupersymmetric Rotating Black Hole in a Compactified Spacetime
We construct a supersymmetric rotating black hole with asymptotically flat four-dimensional spacetime times a circle, by superposing an infinite number of BMPV black hole solutions at the same distance in one direction. The near horizon structure is the same as that of the five-dimensional BMPV black hole. The rotation of this black hole can exceed the Kerr bound in general relativity (q ≡ a/G4...
متن کاملDeformed Density Matrix and Quantum Entropy of the Black Hole
In the present work the approach-density matrix deformation-earlier developed by the author to study a quantum theory of the Early Universe (Planck's scales) is applied to study a quantum theory of black holes. On this basis the author investigates the information paradox problem, entropy of the black hole remainders after evaporation, and consistency with the holographic principle. The possibi...
متن کاملSpacetime Foam, Holographic Principle, and Black Hole Quantum Computers
Spacetime foam, also known as quantum foam, has its origin in quantum fluctuations of spacetime. Arguably it is the source of the holographic principle, which severely limits how densely information can be packed in space. Its physics is also intimately linked to that of black holes and computation. In particular, the same underlying physics is shown to govern the computational power of black h...
متن کاملSpacetime structure of an evaporating black hole in quantum gravity
The impact of the leading quantum gravity effects on the dynamics of the Hawking evaporation process of a black hole is investigated. Its spacetime structure is described by a renormalization group improved Vaidya metric. Its event horizon, apparent horizon, and timelike limit surface are obtained taking the scale dependence of Newton’s constant into account. The emergence of a quantum ergosphe...
