Magneto tunnel conductance across twisted Weyl semimetal junctions
arXiv:2408.10586 · doi:10.1103/PhysRevB.110.155155
Abstract
We investigate magnetotransport across an interface between two Weyl semimetals (finite in both directions) whose Weyl nodes project onto two different surfaces which are twisted with respect to each other before being coupled. This gives rise to a novel contribution to the conductance through the junction purely through Fermi arc states, even in the absence of a magnetic field perpendicular to the junction. When the perpendicular magnetic field is included, we find that for a mesoscopic or smaller samples, the transverse Fermi arc states have a significant contribution to the conductance for experimentally relevant fields, and need to be taken into account along with the conductance through the bulk chiral Landau levels.
