Calculation of Magnetoresistance of an Ideal Topological Insulator Using Boltzmann Transport

ORAL

Abstract

The electrical conductivity of a topological surface state is expected to be enhanced due to the suppression of backscattering resulting from spin-momentum locking. We will present numerical calculation of this enhancement factor using Boltzmann transport for an ideal topological insulator with a single Dirac cone in an arbitrary magnetic field and discuss the manifestations of this for a Corbino sample placed in a tilted magnetic field.
