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…

On the temperature of an active nematic

Jay Armas, Akash Jain, Ruben Lier

We employ a novel hydrodynamic framework for active matter coupled to an environment to study the local temperature of an active nematic, assuming proximity to thermal equilibrium.…

Resistive relativistic magnetohydrodynamics without Amperes Law

Ruben Lier, Akash Jain, Jay Armas +1

Resistive magnetohydrodynamics is thought to play a key role in transient astrophysical phenomena such as black hole flares and neutron star magnetospheres. When performing numeric…

Hydrodynamics of thermal active matter

Jay Armas, Akash Jain, Ruben Lier

Active matter concerns many-body systems comprised of living or self-driven agents that collectively exhibit macroscopic phenomena distinct from conventional passive matter. Using…

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…
