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…
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…
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…
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.…
