On chiral responses to geometric torsion

TL;DR

This paper clarifies that geometric torsion does not induce new chiral transport effects but can be interpreted as an aspect of the chiral vortical effect, refining understanding of chiral responses.

Contribution

It demonstrates that torsion-related responses are not novel effects but are equivalent to known chiral vortical phenomena.

Findings

Torsion does not produce new chiral dissipationless transport effects.

Apparent torsion responses are manifestations of the chiral vortical effect.

Abstract

We show that geometric torsion does not lead to new chiral dissipationless transport effects. Instead apparent response to torsion can be viewed as a manifestation of the chiral vortical effect.
