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…

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…

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…
