Gribov ambiguity in asymptotically AdS three-dimensional gravity
Andres Anabalon, Fabrizio Canfora, Alex Giacomini +1
In this paper the zero modes of the de Donder gauge Faddeev-Popov operator for three dimensional gravity with negative cosmological constant are analyzed. It is found that the thre…
Black-hole dynamics in BHT massive gravity
Hideki Maeda
Using an exact Vaidya-type null-dust solution, we study the area and entropy laws for dynamical black holes defined by a future outer trapping horizon in (2+1)-dimensional Bergshoe…
The BTZ spacetime as an algebraic embedding
Steven Willison
A simple algebraic global isometric embedding is presented for the nonrotating BTZ black hole and its counterpart of Euclidean signature. The image of the embedding, in Minkowski s…
Can (Electric-Magnetic) Duality Be Gauged?
Claudio Bunster, Marc Henneaux
There exists a formulation of the Maxwell theory in terms of two vector potentials, one electric and one magnetic. The action is then manifestly invariant under electric-magnetic d…
Scalar solitons and the microscopic entropy of hairy black holes in three dimensions
Francisco Correa, Cristian Martinez, Ricardo Troncoso
General Relativity coupled to a self-interacting scalar field in three dimensions is shown to admit exact analytic soliton solutions, such that the metric and the scalar field are…
Lovelock theories, holography and the fate of the viscosity bound
Xian O. Camanho, Jose D. Edelstein, Miguel F. Paulos
We consider Lovelock theories of gravity in the context of AdS/CFT. We show that, for these theories, causality violation on a black hole background can occur well in the interior…
