Electric-field-induced interferometric resonance of a one-dimensional spin-orbit-coupled electron

Abstract

We consider a one-dimensional spin-orbit-coupled nanowire quantum dot, driven by external electric and magnetic fields, and theoretically formulate an electric mechanism to interfere its electron orbits. Owing to the existence of spin-orbit coupling and a pulsed electric field, different spin-orbit states are shown to interfere with each other, generating intriguing interference-resonant patterns. We also reveal that an in-plane magnetic field does not affect the strength interval of any neighboring resonant peaks, but contributes a weak shift of each peak, which is sensitive to the direction of the magnetic field. We find that this proposed external-field-controlled scheme should be regarded as a new type of quantum-dot-based interferometry. Finally, this interferometry has an important application in precisely measuring relative experimental parameters, such as the Rashba and Dresselhaus spin-orbit-coupling strengths, as well as the Lande-g factor.
