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…
Rotating Curved Spacetime Signatures from a Giant Quantum Vortex
Patrik Švančara, Pietro Smaniotto, Leonardo Solidoro +5
Gravity simulators are laboratory systems where small excitations like sound or surface waves behave as fields propagating on a curved spacetime geometry. The analogy between gravi…
Imperfect draining vortex as analogue extreme compact object
Theo Torres, Sam Patrick, Ruth Gregory
Motivated by recent experimental progress, we study scalar wave propagation over an imperfect draining vortex, which can serve as an analogue for rotating and non-rotating extreme…
Black hole evaporation in de Sitter space
Ruth Gregory, Ian G. Moss, Naritaka Oshita +1
We investigate the evaporation process of a Kerr-de Sitter black hole with the Unruh-Hawking-like vacuum state, which is a realistic vacuum state modelling the evaporation process…
Thermodynamics of Many Black Holes
Ruth Gregory, Zheng Liang Lim, Andrew Scoins
We discuss the thermodynamics of an array of collinear black holes which may be accelerating. We prove a general First Law, including variations in the tensions of strings linking…
Time dependent black holes and scalar hair
Sarah Chadburn, Ruth Gregory
We show how to correctly account for scalar accretion onto black holes in scalar field models of dark energy by a consistent expansion in terms of a slow roll parameter. We find an…
