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 MiliÄka
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…
