On the temperature dependence of quasinormal modes in SYK and holography
Matthew Dodelson, Om Gupta, Márk Mezei +1
It was recently found that the quasinormal modes (or Ruelle--Pollicott resonances) of the SYK model at infinite temperature form a Christmas tree shape, reminiscent of AdS black ho…
All-order fluctuating hydrodynamics of the SYK lattice
Marta Bucca, Akash Jain, Márk Mezei +1
The SYK model has played an important role in recent developments in many-body quantum chaos. We study a spatially local generalisation of it: the SYK lattice. Starting from the no…
Entanglement membrane in the Brownian SYK chain
Márk Mezei, Harshit Rajgadia
There is mounting evidence that entanglement dynamics in chaotic many-body quantum systems in the limit of large subsystems and long times is described by an entanglement membrane…
The entanglement membrane in 2d CFT: reflected entropy, RG flow, and information velocity
Hanzhi Jiang, Márk Mezei, Julio Virrueta
The time evolution of entanglement entropy in generic chaotic many-body systems has an effective description in terms of a minimal membrane, characterised by a tension function. Fo…
On the non-perturbative bulk Hilbert space of JT gravity
Luca V. Iliesiu, Adam Levine, Henry W. Lin +2
What is the bulk Hilbert space of quantum gravity? In this paper, we resolve this problem in 2d JT gravity, both with and without matter, providing an explicit definition of a non-…
