# Anomalous Transport and Generalized Axial Charge

## TL;DR

This paper explores how macroscopic helicities modify axial charge in chiral media, revealing a new chiral effect that does not require initial chiral asymmetry, with implications for magnetic and fermionic charge distribution.

## Contribution

It introduces a novel mechanism linking helical flows to axial charge changes without initial chirality, supported by a toy model and analysis of magnetic helicity effects.

## Key findings

- Magnetic reconnections induce persistent zero-mode currents.
- Helical flow transfer affects axial charge distribution.
- Balance between reconnection effects and chiral instability influences charge partitioning.

## Abstract

In this paper we continue studying the modification of the axial charge in chiral media by macroscopic helicities. Recently it was shown that magnetic reconnections result in a persistent current of zero mode along flux tubes. Here we argue that in general a change in the helical part of the generalized axial charge results in the same phenomenon. Thus one may say that there is a novel realization of chiral effects requiring no initial chiral asymmetry. The transfer of flow helicity to zero modes is analyzed in a toy model based on a vortex reconnection in a chiral superfluid. Then, we discuss the balance between the two competing processes effect of reconnections and the chiral instability on the example of magnetic helicity. We argue that in the general case there is a possibility for the distribution of the axial charge between the magnetic and fermionic forms at the end of the instability.
