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…
Thermodynamics of ideal spin fluids and pseudo-gauge ambiguity
Jay Armas, Akash Jain
Conserved currents of relativistic spin fluids derived from microscopic models are known to violate local thermodynamic relations. We present a systematic analysis of pseudo-gauge…
Higher-group global symmetry and the bosonic M5 brane
Jay Armas, Giorgos Batzios, Akash Jain
Higher-group symmetries are combinations of higher-form symmetries which appear in various field theories. In this paper, we explain how higher-group symmetries arise in 10d and 11…
Schwinger-Keldysh effective field theory for stable and causal relativistic hydrodynamics
Akash Jain, Pavel Kovtun
We construct stable and causal effective field theories (EFTs) for describing statistical fluctuations in relativistic diffusion and relativistic hydrodynamics. These EFTs are full…
