TL;DR: In this article, the authors presented an explicit approach that allows us to reconstruct exact four-dimensional Einstein spacetimes which are algebraically special with respect to Petrov's classification using the asymptotic form of the bulk Weyl tensor.

TL;DR: In this paper, the classical equations of gravity in AdS themselves hold the key to understand their holographic origin in the form of a strongly coupled large N QFT whose algebra of local operators can be generated by a few trace elements.

TL;DR: In this article, the authors developed a Mitzenmacher-Israel-Stewart formalism for describing a superfluid out of equilibrium by including the Goldstone boson and the condensate together with the hydrodynamic modes as the effective degrees of freedom.

TL;DR: A simple phenomenological model of the black hole as a lattice of interacting nearly AdS_2 throats with gravitational hair charges propagating over the lattice is constructed and the Hayden-Preskill protocol of decoding infalling information is discussed.

TL;DR: In this paper, the nonequilibrium evolution in a boost-invariant Bjorken flow of a hybrid viscous fluid model containing two interacting components with different viscosities, such that they represent strongly and weakly self-coupled sectors, is characterized by a hydrodynamic attractor which has an early-time behavior that is reminiscent of the so-called bottom-up thermalization scenario in heavy-ion collisions.
