Out-of-time-order hydrodynamics and scrambling
Marta Bucca, Akash Jain, Márk Mezei +1
Hydrodynamics as an effective field theory (EFT) has been immensely successful for predicting the behaviour of time-ordered correlation functions in the long-time, large-distance r…

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…

Nonlinear soft mode action for the large- SYK model
Marta Bucca, Márk Mezei
The physics of the SYK model at low temperatures is dominated by a soft mode governed by the Schwarzian action. In arXiv:1604.07818 the linearised action was derived from the soft…
