Spin-orbit-driven coherent oscillations in a few-electron quantum dot

Abstract

We propose an experiment to observe coherent oscillations in a single quantum dot with the oscillations driven by spin-orbit interaction. This is achieved without spin-polarised leads, and relies on changing the strength of the spin-orbit coupling via an applied gate pulse. We derive an effective model of this system which is formally equivalent to the Jaynes-Cummings model of quantum optics. For parameters relevant to a InGaAs dot, we calculate a Rabi frequency of 2 GHz.
