On Universality of Ergoregion Mergers
Henriette Elvang, Pau Figueras, Gary T. Horowitz +2
We study mergers of ergoregions in -dimensional vacuum gravity. At the merger point, where the ergosurfaces bounding each ergoregion just touch, solutions exhibit universal be…

Extremal vacuum black holes in higher dimensions
Pau Figueras, Hari K Kunduri, James Lucietti +1
We consider extremal black hole solutions to the vacuum Einstein equations in dimensions greater than five. We prove that the near-horizon geometry of any such black hole must poss…

Holographic entanglement entropy for disconnected regions
Veronika E. Hubeny, Mukund Rangamani
We present a simple derivation of the entanglement entropy for a region made up of a union of disjoint intervals in 1+1 dimensional quantum field theories using holographic techniq…
