Soft hairy warped black hole entropy
Daniel Grumiller, Philip Hacker, Wout Merbis
We reconsider warped black hole solutions in topologically massive gravity and find novel boundary conditions that allow for soft hairy excitations on the horizon. To compute the a…
Saturation of the Quantum Null Energy Condition in Far-From-Equilibrium Systems
Christian Ecker, Daniel Grumiller, Wilke van der Schee +1
The Quantum Null Energy Condition (QNEC) is a new local energy condition that a general Quantum Field Theory (QFT) is believed to satisfy, relating the classical null energy condit…
New entropy formula for Kerr black holes
Hernan Gonzalez, Daniel Grumiller, Wout Merbis +1
We introduce a new entropy formula for Kerr black holes inspired by recent results for 3-dimensional black holes and cosmologies with soft Heisenberg hair. We show that also Kerr-T…
Menagerie of AdS boundary conditions
Daniel Grumiller, Robert McNees, Jakob Salzer +2
We consider different sets of AdS boundary conditions for the Jackiw-Teitelboim model in the linear dilaton sector where the dilaton is allowed to fluctuate to leading order at…
Log corrections to entropy of three dimensional black holes with soft hair
Daniel Grumiller, Alfredo Perez, David Tempo +1
We calculate log corrections to the entropy of three-dimensional black holes with "soft hairy" boundary conditions. Their thermodynamics possesses some special features that preclu…
Horizon fluff, semi-classical black hole microstates - Log-corrections to BTZ entropy and black hole/particle correspondence
H. Afshar, D. Grumiller, M. M. Sheikh-Jabbari +1
According to the horizon fluff proposal microstates of a generic black hole belong to a certain subset of near horizon soft hairs that cannot be extended beyond the near horizon re…
Most general flat space boundary conditions in three-dimensional Einstein gravity
Daniel Grumiller, Wout Merbis, Max Riegler
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 fun…
Higher-Spin Flat Space Cosmologies with Soft Hair
Martin Ammon, Daniel Grumiller, Stefan Prohazka +2
We present and discuss near horizon boundary conditions for flat space higher-spin gravity in three dimensions. As in related work our boundary conditions ensure regularity of the…
Three-dimensional Spin-3 Theories Based on General Kinematical Algebras
Eric Bergshoeff, Daniel Grumiller, Stefan Prohazka +1
We initiate the study of non- and ultra-relativistic higher spin theories. For sake of simplicity we focus on the spin-3 case in three dimensions. We classify all kinematical algeb…
