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…
Finite stress-tensor moment tomography of boundary-graviton coherences
Dyuman Bhattacharya, Robert B. Mann
Einstein gravity in 2+1 dimensions is a topological theory that does not admit the existence of local bulk gravitons. However, gravity with Brown-Henneaux boundary…
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…
Holographic Thermodynamics of Dyonic Dilaton AdS Black Holes
Muhammad Fitrah Alfian Rangga Sakti, Robert Mann, Piyabut Burikham
We investigate the holographic dual of the extended bulk thermodynamics of dyonic dilaton AdS black holes by allowing both the cosmological constant and Newton's gravitational cons…
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…
Multicritical points of gravitational solitons and a black hole in four dimensions
Moaathe Belhaj Ahmed, Moisés Bravo-Gaete, Robert B. Mann +1
We present the first realization of multicritical points in four-dimensional general relativity, specifically within the context of Plebański nonlinear electrodynamics, using a pol…
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…
Probing holographic conformal field theories
Ming Zhang, Jiayue Yang, Dyuman Bhattacharya +1
We embed relativistic quantum information protocols in AdS/CFT: an Unruh-DeWitt detector coupled to a local primary of a holographic CFT has a reduced state fixed by the universal…
