Physical Review D, 1996 One would expect spacetime to have a foam-like structure on the Planck scale with a very high topology. If spacetime is simply connected (which is assumed in this paper), the non-trivial homology occurs in dimension two, and spacetime can be regarded as being essentially the topological sum of $S^2\times S^2$ and $K3$ bubbles.

Thick Domain Walls in AdS Black Hole Spacetimes [PDF]
, 2006 Equations of motion for a real self-gravitating scalar field in the background of a black hole with negative cosmological constant were solved numerically.

International Journal of Modern Physics D, 2003 Production of high-energy gravitational objects is a common feature of gravitational theories. The primordial universe is a natural setting for the creation of black holes and other nonperturbative gravitational entities. Cosmic black holes can be used to probe physical properties of the very early universe which would usually require the knowledge of

Thermodynamics and phase transition of BTZ black hole in a cavity
Nuclear Physics B, 2022 In this paper, we study the thermodynamics and phase transition of a BTZ black hole in a finite space region, namely a cavity. By imposing a temperature-fixed boundary condition on the wall of the cavity and evaluating the Euclidean action, we derive the

Stability analysis of sonic horizons in Bose-Einstein condensates [PDF]
, 2006 We examine the linear stability of various configurations in Bose-Einstein condensates with sonic horizons. These configurations are chosen in analogy with gravitational systems with a black hole horizon, a white hole horizon and a combination of both ...

Ruppeiner geometry and thermodynamic phase transition of the black hole in massive gravity
European Physical Journal C: Particles and Fields, 2021 The phase transition and thermodynamic geometry of a 4-dimensional AdS topological charged black hole in de Rham, Gabadadze and Tolley (dRGT) massive gravity have been studied.

International Journal of Modern Physics D, 2021 In this paper, we consider a version of the Hayden–Preskill thought experiment in which the message thrown into the black hole is itself a smaller black hole. We then discuss the implications of the existence of a recovery channel for this black hole message at asymptotic infinity, resulting in a sharpening of the black hole information paradox for ...

BLACK HOLE UNCERTAINTIES [PDF]
Modern Physics Letters A, 1993 In this work the quantum theory of two-dimensional dilaton black holes is studied using the Wheeler-De Witt equation. The solutions correspond to wave functions of the black hole. It is found that for an observer inside the horizon, there are uncertainty relations for the black hole mass and a parameter in the metric determining the Hawking flux. Only

Disturbing the Black Hole [PDF]
, 1998 I describe some examples in support of the conjecture that the horizon area of a near equilibrium black hole is an adiabatic invariant. These include a Schwarzschild black hole perturbed by quasistatic scalar fields (which may be minimally or ...
