Soft hairy horizons in three spacetime dimensions
Hamid Afshar, Daniel Grumiller, Wout Merbis +3
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, and…
Exploring nonlocal observables in shock wave collisions
Christian Ecker, Daniel Grumiller, Philipp Stanzer +2
We study the time evolution of 2-point functions and entanglement entropy in strongly anisotropic, inhomogeneous and time-dependent N=4 super Yang-Mills theory in the large N and l…
Most general AdS_3 boundary conditions
Daniel Grumiller, Max Riegler
We consider the most general asymptotically anti-de Sitter boundary conditions in three-dimensional Einstein gravity with negative cosmological constant. The metric contains in tot…
Higher Spin Black Holes with Soft Hair
Daniel Grumiller, Alfredo Perez, Stefan Prohazka +2
We construct a new set of boundary conditions for higher spin gravity, inspired by a recent "soft Heisenberg hair"-proposal for General Relativity on three-dimensional Anti-de Sitt…
Aspects of AdS holography with non-constant dilaton
Daniel Grumiller, Jakob Salzer, Dmitri Vassilevich
In this proceedings contribution we summarize and discuss results of Refs. \cite{Grumiller:2013swa, Grumiller:2015vaa} in the light of recent developments in holog…
Black Hole Horizon Fluffs: Near Horizon Soft Hairs as Microstates of Three Dimensional Black Holes
H. Afshar, D. Grumiller, M. M. Sheikh-Jabbari
We provide the first explicit proposal for all microstates of generic black holes in three dimensions (of Banados-Teitelboim-Zanelli-type): black hole microstates, termed "horizon…
Soft Heisenberg hair on black holes in three dimensions
Hamid Afshar, Stephane Detournay, Daniel Grumiller +4
Three-dimensional Einstein gravity with negative cosmological constant admits stationary black holes that are not necessarily spherically symmetric. We propose boundary conditions…
Near-Horizon Geometry and Warped Conformal Symmetry
Hamid Afshar, Stéphane Detournay, Daniel Grumiller +1
We provide boundary conditions for three-dimensional gravity including boosted Rindler spacetimes, representing the near-horizon geometry of non-extremal black holes or flat space…
