The present status of the quasi-local mass, energy-momentum and angular-momentum
constructions in general relativity is reviewed. First, the general ideas, concepts, and …

Heavy ion collision experiments recreating the quark-gluon plasma that filled the nascent
universe have established that it is a nearly perfect liquid that flows with such minimal …

The IR dynamics of effective holographic theories capturing the interplay between charge
density and the leading relevant scalar operator at strong coupling are analyzed. Such …

The symmetry algebra of asymptotically flat spacetimes at null infinity in three dimensions is
the semi-direct sum of the infinitesimal diffeomorphisms on the circle with an Abelian ideal of …

It was recently proposed that a large N limit of a family of minimal model CFTs is dual to a
certain higher spin gravity theory in AdS 3, where the't Hooft coupling constant of the CFT is …

A bstract New boundary conditions for asymptotically flat spacetimes are given at spatial
infinity. These boundary conditions are invariant under the BMS group, which acts non …

An exact four-dimensional black hole solution of gravity with a minimally coupled self-
interacting scalar field is reported. The event horizon is a surface of negative constant …

We obtain electrically charged black hole solutions of the Einstein equations in arbitrary
dimensions with a nonlinear electrodynamics source. The matter source is derived from a …

We consider the Einstein-scalar-Gauss-Bonnet theory in the presence of a cosmological
constant Λ, either positive or negative, and look for novel, regular black-hole solutions with a …

We consider the Einstein-scalar-Gauss-Bonnet theory, and study the case where a negative
cosmological constant is replaced by a more realistic, negative scalar-field potential. We …
