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…

Higgs Vacuum Decay from Particle Collisions?
Leopoldo Cuspinera, Ruth Gregory, Katie Marshall +1
We examine the effect of large extra dimensions on black hole seeded vacuum decay using the Randall-Sundrum model as a prototype for warped extra dimensions. We model the braneworl…
