Charge redistribution from anomalous magnetovorticity coupling

TL;DR

This paper explores how vorticity and magnetic fields in a chiral fluid cause charge redistribution and axial currents, revealing transport coefficients linked to quantum anomalies, independent of temperature and chemical potential.

Contribution

It introduces a novel transport phenomenon arising from magnetovorticity coupling in chiral fluids, with coefficients derived from both energy-shift and diagrammatic methods.

Findings

Transport coefficients proportional to the anomaly coefficient.

Transport phenomena are independent of temperature and chemical potential.

Results suggest a connection to quantum anomaly.

Abstract

We investigate novel transport phenomena in a chiral fluid originated from an interplay between a vorticity and strong magnetic field, which induces a redistribution of vector charges in the system and an axial current along the magnetic field. The corresponding transport coefficients are obtained from an energy-shift argument for the chiral fermions in the lowest Landau level (LLL) due to a spin-vorticity coupling and also from diagrammatic computations on the basis of the linear response theory. Based on consistent results from the both methods, we observe that the transport coefficients are proportional to the anomaly coefficient and are independent of temperature and chemical potential. We therefore speculate that these transport phenomena are connected to quantum anomaly.
