Energy of asymptotically AdS black holes in Exotic Massive Gravity and its log-extension
Robert B. Mann, Julio Oliva, S. N. Sajadi
Recently a new three-dimensional theory of gravity, dubbed Exotic Massive Gravity, was proposed as a unitary theory both in the bulk as well as in the dual CFT. This is the second…
Snapping swallowtails in accelerating black hole thermodynamics
Niloofar Abbasvandi, Wan Cong, David Kubiznak +1
The thermodynamic behaviour of a charged and accelerating AdS black hole is studied in the context of extended phase space with variable cosmological constant. When compared to the…
Thermodynamics of Charged, Rotating, and Accelerating Black Holes
Andres Anabalon, Finnian Gray, Ruth Gregory +2
We show how to obtain a consistent thermodynamic description of accelerating asymptotically AdS black holes, extending our previous results by including charge and rotation. We fin…
Energy-momentum tensor and metric near the Schwarzschild sphere
Valentina Baccetti, Robert B. Mann, Sebastian Murk +1
Regularity of the horizon radius of a collapsing body constrains a limiting form of a spherically-symmetric energy-momentum tensor near it. Its non-zero limit belongs to one…
Bose-Einstein Condensates as Gravitational Wave Detectors
Matthew P. G. Robbins, Niayesh Afshordi, Robert B. Mann
We investigate a Bose-Einstein condensate (BEC) as a gravitational wave detector, and study its sensitivity by optimizing the properties of the condensate and the measurement durat…
Intrinsic curvature and topology of shadows in Kerr spacetime
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
From the viewpoint of differential geometry and topology, we investigate the characterization of the shadows in a Kerr spacetime. Two new quantities, the length of the shadow bound…
Gravitational Lensing by Black Holes in Einsteinian Cubic Gravity
Mohammad Bagher Jahani Poshteh, Robert B. Mann
We investigate the predictions of Einsteinian Cubic Gravity (ECG) for the lensing effects due to supermassive black holes at the center of Milky Way and other galaxies. Working in…
Entanglement Harvesting with Moving Mirrors
Wan Cong, Erickson Tjoa, Robert B. Mann
We study the phenomenon of entanglement extraction from the vacuum of a massless scalar field in dimensional spacetime in presence of a moving Dirichlet boundary condition,…
Shadow and Deflection Angle of Rotating Black Holes in Perfect Fluid Dark Matter with a Cosmological Constant
Sumarna Haroon, Mubasher Jamil, Kimet Jusufi +2
The presence of dark matter around a black hole remarkably affects its spacetime. We consider the effects of dark matter on the shadow of a new solution to the Einstein equations t…
Unruh-DeWitt detectors and entanglement: the anti-de Sitter space
Keith K. Ng, Robert B. Mann, Eduardo Martin-Martinez
We investigate entanglement harvesting in AdS. Applying the general results of [Phys. Rev. D 97, 125011 (2018)], we consider two scenarios: one where two particle detectors are…
Entangling detectors in anti-de Sitter space
Laura J. Henderson, Robie A. Hennigar, Robert B. Mann +2
We examine in -dimensional anti-de Sitter (AdS) space the phenomena of entanglement harvesting - the process in which a pair of detectors (two-level atoms) extract entanglem…
Reverse Hawking-Page Phase Transition in de Sitter Black Holes
Saoussen Mbarek, Robert B. Mann
In the context of black hole chemistry, we study the thermodynamics of asymptotically de Sitter black holes with conformal scalar hair in Einstein gravity. The hair parameter allow…
NUTs and bolts beyond Lovelock
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We construct a plethora of new Euclidean AdS-Taub-NUT and bolt solutions of several four- and six-dimensional higher-curvature theories of gravity with various base spaces $\mathca…
Entanglement harvesting from multiple massless scalar fields and divergences in Unruh-DeWitt detector models
Allison M. Sachs, Robert B. Mann, Eduardo Martin-Martinez
We analyze scenarios in which pairs of Unruh-DeWitt-like detectors interact with scalar field(s) with bi-linear and quadratic coupling. For all cases -- real scalar fields, charged…

We present several results concerning the free energy of odd-dimensional conformal field theories (CFTs) on squashed spheres. First, we propose a formula which computes this quanti…
Scalar and fermionic Unruh Otto engines
Finnian Gray, Robert B. Mann
We investigate the behaviour of quantum heat engines, in which a qubit is put through the quantum equivalent of the Otto cycle and the heat reservoirs are due to the Unruh effect.…

Keith K. Ng, Robert B. Mann, Eduardo Martin-Martinez
We present a new technique for computing entanglement harvesting with Unruh-DeWitt particle detectors. The method is particularly useful in cases where analytic solutions are rare…

Abdulrahim Al Balushi, Wan Cong, Robert B. Mann
An open question in experimental physics is the characterization of gravitational effects in quantum regimes. We propose an experimental set-up that uses well-tested techniques in…
