Chiral charge transfer along magnetic field lines in a Weyl superconductor

TL;DR

This paper reveals a chiral-dependent conductance signature along magnetic vortices in Weyl superconductors, linking magnetic field orientation to the underlying Weyl point chirality in the electronic structure.

Contribution

It introduces a novel way to detect chirality in Weyl superconductors through conductance measurements influenced by magnetic field orientation.

Findings

Conductance varies with magnetic field direction relative to Weyl point chirality.

Chirality-dependent signatures can be observed along magnetic vortices.

The results provide a new method to probe Weyl fermion properties in superconductors.

Abstract

We identify a signature of chirality in the electrical conduction along magnetic vortices in a Weyl superconductor: The conductance depends on whether the magnetic field is parallel or antiparallel to the vector in the Brillouin zone that separates Weyl points of opposite chirality.
