Transport, entanglement, and chaos in chiral quantum fluids far from equilibrium — •Matthias Kaminski¹, Casey Cartwright¹, Jana Ingram¹, Roshan Koirala¹, and Martin Ammon² — ¹Department of Physics and Astronomy, University of Alabama, Tuscaloosa, AL 35487, USA — ²Theoretisch-Physikalisches Institut, Friedrich-Schiller University of Jena, 07743 Jena, Germany

First, applying recently developed methods, we systematically construct and complete the hydrodynamic description of charged chiral quantum fluids in strong external magnetic fields as an effective field theory. This description includes the effect of chiral anomalies, magnetization and polarization. Novel transport effects arise.

Second, as a proof of existence, within a holographic (gauge/gravity correspondence) model, we compute most of the linear response coefficients describing these transport effects. The holographic model on the gravity side consists of charged magnetic black hole solutions to Einstein-Maxwell-Chern-Simons theory.

Third, as the main part of this work, we drive that same gravitational model far from equilibrium through rapid mass accretion. From this, we compute entanglement entropy and correlation functions of the corresponding fluid far from equilibrium. We derive relations between the linear response coefficients mentioned above, such as diffusivity, and the quantities characterizing the chaotic behavior of the system, such as the butterfly velocity.
