The endless journey towards the horizon of a quantum black hole
Victor Franken, Thomas G. Mertens, Bruno de S. L. Torres
It is a problem of great importance in quantum gravity whether quantum effects lead to nontrivial structure near black hole horizons, and if their interiors are emergent features o…
Quantum gravity around ultracold black holes from DSSYK
Francesca Mariani, Thomas G. Mertens, Jacopo Papalini +1
We propose a quantum description of the ultracold Reissner-Nordström de Sitter black hole via a specific flat space limit of the double-scaled SYK model. Fluctuations in this regim…
Falling through the horizon of a quantum black hole
Victor Franken, Thomas G. Mertens, Bruno de S. L. Torres
We study quantum-gravitational effects on the response of an infalling detector as it crosses the horizon of a near-extremal black hole in the framework of quantum JT gravity. Thes…
Fiducial observers and the thermal atmosphere in the black hole quantum throat
Thomas G. Mertens, Thomas Tappeiner, Bruno de S. L. Torres
We propose a construction of fiducial observers in the throat region of near-extremal black holes within the framework of JT quantum gravity, leading to a notion of local observers…
Minimal Factorization of Chern-Simons Theory -- Gravitational Anyonic Edge Modes
Thomas G. Mertens, Qi-Feng Wu
One approach to analyzing entanglement in a gauge theory is embedding it into a factorized theory with edge modes on the entangling boundary. For topological quantum field theories…
Quantum group origins of edge states in double-scaled SYK
Andreas Belaey, Thomas G. Mertens, Thomas Tappeiner
Double-scaled SYK (DSSYK) is known to have an underlying quantum group theoretical description. We precisely pinpoint the quantum group structure, improving upon earlier work in th…
Gravitational wavefunctions in JT supergravity
Andreas Belaey, Francesca Mariani, Thomas G. Mertens
We determine explicit expressions for the continuous two-sided gravitational wavefunctions in supersymmetric versions of JT gravity, focusing mainly on JT supergrav…
Branes in JT (super)gravity from group theory
Andreas Belaey, Francesca Mariani, Thomas G. Mertens
In this work, we revisit the end-of-the-world (EOW) brane amplitudes in JT gravity from a BF gauge theoretic perspective. Observing and identifying the correct group theoretic ingr…
