Quantized chiral magnetic current from reconnections of magnetic flux

TL;DR

This paper proposes a novel mechanism for the chiral magnetic effect where magnetic flux reconnections generate a quantized current without initial chirality imbalance, linking magnetic helicity changes to observable effects.

Contribution

It introduces a new, helicity-based mechanism for the chiral magnetic effect that does not depend on initial chirality imbalance, with quantized current outcomes.

Findings

Current is generated by magnetic flux reconnections.

The resulting current is quantized.

The mechanism links magnetic helicity change to observable current.

Abstract

We introduce a new mechanism for the chiral magnetic effect that does not require an initial chirality imbalance. The chiral magnetic current is generated by reconnections of magnetic flux that change the magnetic helicity of the system. The resulting current is entirely determined by the change of magnetic helicity, and it is quantized.
