Recently, we have introduced a novel inter‐subband‐induced spin‐orbit (s‐o) coupling (cond‐mat/0607218) arising in symmetric wells with at least two subbands. This new s‐o coupling gives rise to an usual zitterbewegung – i.e. the semiconductor analog to the relativistic trembling motion of electrons – with cycloidal motion without magnetic fields. Here we complement these findings by explicitly deriving expressions for the corresponding zitterbewegung in spin space. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
