Survey of spinning test particle orbits in Kerr spacetime
TL;DR: In this article, the authors investigate the dynamics of the Papapetrou equations in Kerr spacetime and show that the chaotic solutions either do not correspond to realistic astrophysical systems, or involve a breakdown of the test-particle approximation leading to the PPE, or both.
Journal ArticleDOI
Extremal and nonextremal Kerr/CFT correspondences
TL;DR: In this paper, the authors derive the Kerr/CFT correspondence without first taking the near-horizon extremal Kerr limit, and then present an alternative approach, based on a stretched Killing horizon, in which the full entropy is obtained and the temperature and central charge remain well-behaved even in the nonextremal case.

Stochastic semiclassical fluctuations in Minkowski spacetime
Rosario Martín,Enric Verdaguer +1 more
TL;DR: In this article, the semiclassical Einstein-Langevin equations for the dynamics of stochastic perturbations of the metric induced by quantum stress-energy fluctuations of matter fields in a given state are considered on the background of the ground state of semiclassically gravity, namely, Minkowski spacetime and a scalar field in its vacuum state.
Journal ArticleDOI
Concept of temperature in multi-horizon spacetimes: analysis of Schwarzschild–De Sitter metric
TL;DR: In this article, the conditions under which a global temperature can exist for a spacetime with two horizons using the example of Schwarzschild-De Sitter (SDS) spacetime was examined.
Journal ArticleDOI
Thermal Fluctuations and Black Hole Entropy
Gilad Gour,A. J. M. Medved +1 more
TL;DR: In this paper, the authors consider the effect of thermal fluctuations on the entropy of both neutral and charged black holes and show that the leading-order quantum correction to the entropy can consistently be expressed as the logarithm of the classical quantity.
