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…
