All-electrical measurement of relative strength of spin-orbit interactions in interacting quantum wires

Abstract

We present a theoretical analysis of the ac transport property of quantum wires with Coulomb interaction included using the Luttinger liquid theory. We make experimentally testable predictions of a sensitive dependence of the ac conductance on the wire orientation. The ac conductance displays oscillating behavior as the frequency of the external voltage increases. The oscillation period provides us with a new way of measuring the relative strength of the Rashba and Dresselhaus spin-orbit interactions. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
