Analytic detector responses and entanglement in constant-curvature spacetimes
Dyuman Bhattacharya, Jiayue Yang, Ming Zhang +1
We derive analytic response functions for Unruh--DeWitt detectors coupled to real, massless, conformally coupled scalar fields, to distinguish the effects of the field spectrum and…
On the Classical, Penrose, and Reverse Isoperimetric Inequalities in Black Holes: Insights From AdS to Flat Riemannian Backgrounds
Robert B. Mann, Behnam Pourhassan, Ali Dehghani
A collection of evidence is presented showing that the conjectured reverse isoperimetric inequality (RII) for asymptotically anti-de Sitter (AdS) as well as de Sitter (dS) black ho…
Acceleration and Rotation in Three Dimensions
Cameron R D Bunney, Ruth Gregory, Robert B Mann
We present a new family of exact solutions representing accelerating, rotating, point particle and black hole solutions in three-dimensional Einstein gravity. We investigate their…
Soliton-Black Hole Phase Transitions in the Presence of String Clouds
Ziqing Chen, Robert B. Mann
We study soliton-black hole phase transitions in asymptotically AdS planar spacetimes sourced by a cloud of strings. In the planar background, the string cloud exhibits a brush-lik…
From (Hidden) Symmetries to Stealth Solutions
David Kubiznak, Robert B. Mann, Marek Milička
In a recent paper, Arxiv:2605.23077, we have demonstrated that (conformal) Killing vectors give rise to stealth vector solutions of a specific bumblebee-type Proca theory supplemen…
Nonperturbative Danielson-Satishchandran-Wald Decoherence with Unruh-DeWitt detectors
Levy B. N. Batista, André G. S. Landulfo, Robert B. Mann +1
Recently, Danielson, Satishchandran, and Wald (DSW) have proposed a novel source of decoherence for uniformly accelerated charges and masses in spatial superposition in spacetimes…
Normal modes of charged AdS solitons
Mengqi Lu, Ming Zhang, Robert B. Mann
We study massive charged scalar field perturbations in four- and five- dimensional charged anti-de Sitter soliton spacetimes. Appropriate boundary conditions are established via a…
C-metric in a (nut)shell
Cameron R D Bunney, Robert B Mann
We present a comprehensive study of the C-metric in dimensions, placing it within a shell of stress energy and matching it to an exterior vacuum AdS metric. The C-metri…
Gravitationally Collapsing Shells in (2+1) Dimensions
R. B. Mann, J. J. Oh
We study gravitationally collapsing models of pressureless dust, fluids with pressure, and the generalized Chaplygin gas (GCG) shell in (2+1)-dimensional spacetimes. Various collap…
