Finite-volume scheme for first-order viscoresistive relativistic magnetohydrodynamics
Ruben Lier, Jay Armas, Oliver Porth
We present a numerical implementation of dissipative relativistic magnetohydrodynamics based on Bemfica-Disconzi-Noronha-Kovtun (BDNK) theory, in which first-order corrections rend…
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.…
Chiral anomaly from (anomalous) spin hydrodynamics
Jay Armas, Giorgos Batzios
We show that the low energy fluctuations of spinning black Dp branes are described by a theory of spin hydrodynamics on a spacetime in whi…
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…
Hydrodynamics for charge density waves and their holographic duals
Jay Armas, Akash Jain
We formulate a theory of dissipative hydrodynamics with spontaneously broken translations, describing charge density waves in a clean isotropic electronic crystal. We identify a no…
