We explore the spacetime structure near nonextremal horizons in any spacetime dimension
greater than two and discover a wealth of novel results:(i) Different boundary conditions are …

A bstract Assuming the existence of a field theory in D dimensions dual to (D+ 1)-
dimensional flat space, governed by the asymptotic symmetries of flat space, we make some …

We present the analytical calculation of entanglement entropy for a class of two-dimensional
field theories governed by the symmetries of the Galilean conformal algebra, thus providing …

Three-dimensional Einstein gravity with a negative cosmological constant admits stationary
black holes that are not necessarily spherically symmetric. We propose boundary conditions …

A bstract The conformal symmetry algebra in 2D (Diff (S 1)⊕ Diff (S 1)) is shown to be
related to its ultra/non-relativistic version (BMS 3≈ GCA 2) through a nonlinear map of the …

We discuss some aspects of soft hairy black holes and a new kind of “soft hairy
cosmologies,” including a detailed derivation of the metric formulation, results on flat space …

We consider the most general asymptotically flat boundary conditions in three-dimensional
Einstein gravity in the sense that we allow for the maximal number of independent free …

A bstract We provide boundary conditions for three-dimensional gravity including boosted
Rindler spacetimes, representing the near-horizon geometry of non-extremal black holes or …

We calculate holographically arbitrary n-point correlators of the boundary stress tensor in
three-dimensional Einstein gravity with negative or vanishing cosmological constant. We …

A bstract In this paper we perform the Hamiltonian reduction of the action for three-
dimensional Einstein gravity with vanishing cosmological constant using the Chern-Simons …
