Abstract

Building on the discovery that a Weyl superconductor in a magnetic field supports chiral Landau-level motion along the vortex lines, we investigate its transport properties out of equilibrium. We show that the vortex lattice carries an electric current I=12(Q2eff/h)(Φ/Φ0)V between two normal-metal contacts at voltage difference V, with Φ the magnetic flux through the system, Φ0 the superconducting flux quantum, and Qeff<e the renormalized charge of the Weyl fermions in the superconducting Landau level. Because the charge renormalization is energy dependent, a nonzero thermoelectric coefficient appears even in the absence of energy-dependent scattering processes.
