Three-dimensional Weyl fermions have a definite chirality, given by the ± sign in the Weyl Hamiltonian ±p ·σ. Three spatial dimensions are essential, if p ·σ = pxσx+pyσy contains only two Pauli matrices, then +p·σ and −p ·σ can be transformed into each other by a unitary transformation (conjugation with σz). The chirality is therefore a characteristic feature of 3D Weyl semimetals, not shared by 2D graphene. The search for observable signatures of chirality is a common theme in the study of…

It is shown that superconductivity offers a way to avoid this cancellation of the chiral magnetic effect by means of a flux bias that gaps out a Weyl cone jointly with its particle-hole conjugate.

Topologically Protected Landau Level in the Vortex Lattice of a Weyl Superconductor.

The chirality of the Weyl fermions protects the zeroth Landau level by means of a topological index theorem, and the heat conductance parallel to the magnetic field has the universal value G=1/2g_{0}Φ/Φ_{0}, with Φ as the magnetic flux through the system, Φ{0} as the superconducting flux quantum, and g_0 as the thermal conductance quantum.
