Flat space holography and complex SYK
Hamid Afshar, Hernan Gonzalez, Daniel Grumiller +1
We provide the first steps towards a flat space holographic correspondence in two bulk spacetime dimensions. The gravity side is described by a conformally transformed version of t…
Interpolating Between Asymptotic and Near Horizon Symmetries
D. Grumiller, M. M. Sheikh-Jabbari, C. Troessaert +1
We develop basic tools and matching conditions to interpolate between asymptotic and near horizon symmetries. We focus on black holes in three dimensions. In particular, we match B…
Spacetime structure near generic horizons and soft hair
Daniel Grumiller, Alfredo Pérez, M. M. Sheikh-Jabbari +2
We explore the spacetime structure near non-extremal horizons in any spacetime dimension greater than two and discover a wealth of novel results: 1. Different boundary conditions a…
Local quantum energy conditions in non-Lorentz-invariant quantum field theories
Daniel Grumiller, Pulastya Parekh, Max Riegler
We provide the first example of local quantum energy conditions in quantum field theories that are not Lorentz invariant. We focus on field theories in two dimensions with infinite…
Near horizon dynamics of three dimensional black holes
Daniel Grumiller, Wout Merbis
We perform the Hamiltonian reduction of three dimensional Einstein gravity with negative cosmological constant under constraints imposed by near horizon boundary conditions. The th…
Quantum Null Energy Condition and its (non)saturation in 2d CFTs
Christian Ecker, Daniel Grumiller, Wilke van der Schee +2
We consider the Quantum Null Energy Condition (QNEC) for holographic conformal field theories in two spacetime dimensions (CFT). We show that QNEC saturates for all states dual…
