Non-Local Coulomb Drag in Weyl Semimetals

Abstract

Non-locality is one of the most striking signatures of the topological nature of Weyl semimetals. We propose to probe the non-locality in these materials via a measurement of a magnetic field dependent Coulomb drag between two sheets of graphene which are separated by a three-dimensional slab of Weyl semimetal. We predict a new mechanism of Coulomb drag, based on cyclotron orbits that are split between opposite surfaces of the semi-metal. In the absence of impurity scattering between different Weyl nodes, this mechanism does not decay with the thickness of the semi-metal.
