Are Superentropic black holes superentropic?
Michael Appels, Leopoldo Cuspinera, Ruth Gregory +2
We study a critical limit in which asymptotically-AdS black holes develop maximal conical deficits and their horizons become non-compact. When applied to stationary rotating black…
Higgs Vacuum Decay in a Braneworld
Leopoldo Cuspinera, Ruth Gregory, Katie M Marshall +1
We examine the effect of large extra dimensions on vacuum decay in the Randall-Sundrum (RS) braneworld paradigm. We assume the scalar field is confined to the brane, and compute th…
Conical Holographic Heat Engines
Wasif Ahmed, Hong Zhe Chen, Elliott Gesteau +2
We demonstrate that adding a conical deficit to a black hole holographic heat engine increases its efficiency; in contrast, allowing a black hole to accelerate {\it decreases} effi…
Accelerating Black Hole Chemistry
Ruth Gregory, Andrew Scoins
We introduce a new set of chemical variables for the accelerating black hole. We show how these expressions suggest that conical defects emerging from a black hole can be considere…
Rotating Black Holes in Higher Order Gravity
Christos Charmousis, Marco Crisostomi, Ruth Gregory +1
We develop a new technique for finding black hole solutions in modified gravity that have "stealth" hair, i.e., hair whose only gravitational effect is to tune the cosmological con…
Effective field theory for black holes with induced scalar charges
Leong Khim Wong, Anne-Christine Davis, Ruth Gregory
While no-hair theorems forbid isolated black holes from possessing permanent moments beyond their mass, electric charge, and angular momentum, research over the past two decades ha…
