Properties of black holes in non-linear electrodynamics
Lewis Croney, Ruth Gregory, Ansh Gupta +1
We investigate the properties of charged black hole geometries in nonlinear electrodynamics. We focus on the recently reported analytic charged black hole solutions to illustrate t…
Thermodynamics of dyonic black holes in non-linear electrodynamics
Lewis Croney, Ruth Gregory, Carlos J. Ramírez-Valdez
We investigate dyonic black holes in a weak field expansion of non-linear electrodynamics. The breadth of parameter space permits a rich thermodynamic structure, additional turning…
Ultra slow-roll with a black hole
Lewis Croney, Ruth Gregory, Sam Patrick
We investigate ultra slow-roll inflation with a seed black hole in a de Sitter background. By numerically tracking transitions from slow-roll to ultra slow-roll inflation, we find…
Renormalisation group flows connecting a dimensional Hermitian field theory to a -symmetric theory for a fermion coupled to an axion
Lewis Croney, Sarben Sarkar
The renormalisation group flow of a Hermitian field theory is shown to have trajectories which lead to a non-Hermitian Parity-Time () symmetric field theory for an ax…
