Zitterbewegung of electronic wave packets in semiconductor nanostructures — •John Schliemann1, Daniel Loss1, and R.M. Westervelt21University of Basel — 2Havard University

We study the zitterbewegung of electronic wave packets in III-V zinc-blende semiconductor quantum wells due to spin-orbit coupling. Our results suggest a direct experimental proof of this fundamental effect, confirming a long-standing theoretical prediction. For electron motion in a harmonic quantum wire, we find a resonance condition maximizing the zitterbewegung. We also consider the zitterbewegung of heavy holes in quantum wells under the influence of Rashba spin-orbit coupling.
