The BTZ black hole exhibits anti-Hawking phenomena
Laura J. Henderson, Robie A. Hennigar, Robert B. Mann +2
The Unruh effect is a surprising prediction of quantum field theory that asserts accelerating observers perceive a thermal spectrum of particles with a temperature proportional to…
Null hypersurfaces in Kerr-(A)dS spacetimes
Abdulrahim Al Balushi, Robert B. Mann
For many purposes, a three-dimensional foliation of spacetime is more advantageous to understanding its light cone structure. We derive the equations describing such foliations for…
Ruppeiner Geometry, Phase Transitions, and the Microstructure of Charged AdS Black Holes
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
Originally considered for van der Waals fluids and charged black holes [Phys. Rev. Lett. 123, 071103 (2019)], we extend and generalize our approach to higher-dimensional charged Ad…
Thermodynamic Instabilities of Generalized Exotic BTZ Black Holes
Wan Cong, Robert B. Mann
We examine the conjecture that black holes violating the reverse isoperimetric inequality have negative specific heat at constant volume . We test this conjecture on the famil…
Motion of localized sources in general relativity: gravitational self-force from quasilocal conservation laws
Marius Oltean, Richard J. Epp, Carlos F. Sopuerta +2
An idealized "test" object in general relativity moves along a geodesic. However, if the object has a finite mass, this will create additional curvature in the spacetime, causing i…
Finely Split Phase Transitions of Rotating and Accelerating Black Holes
Niloofar Abbasvandi, Wasif Ahmed, Wan Cong +2
We investigate the thermodynamic phase behaviour of rotating and slowly accelerating AdS black holes. While we find some similarities with the non-rotating charged counterparts, su…
Repulsive Interactions and Universal Properties of Charged Anti-de Sitter Black Hole Microstructures
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
The Ruppeiner geometry of thermodynamic fluctuations provides a powerful diagnostic of black hole microstructures. We investigate this for charged AdS black holes and find that whi…
Extended Thermodynamics and Complexity in Gravitational Chern-Simons Theory
Antonia Micol Frassino, Robert B. Mann, Jonas R. Mureika
We study several aspects of the extended thermodynamics of BTZ black holes with thermodynamic mass and angular momentum , for general val…
Critical Phenomena of Born-Infeld-de Sitter Black Holes in Cavities
Fil Simovic, Robert B. Mann
We examine the thermodynamic behaviour of charged, asymptotically de Sitter black holes embedded in a finite-radius isothermal cavity, with a Born-Infeld gauge field replacing the…
Trapped surfaces, energy conditions, and horizon avoidance in spherically-symmetric collapse
Valentina Baccetti, Robert B. Mann, Daniel R. Terno
We consider spherically-symmetric black holes in semiclassical gravity. For a collapsing radiating thin shell we derive a sufficient condition on the exterior geometry that ensures…
Probing geometric information using the Unruh effect in the vacuum
Aida Ahmadzadegan, Fatemeh Lalegani, Achim Kempf +1
We present a new method by which, in principle, it is possible to "see in absolute darkness," i.e., without exchanging any real quanta through quantum fields. This is possible beca…
