Nanospintronics meets relativistic quantum physics: Ubiquity of Zitterbewegung effects
arXiv:0707.3701 · doi:10.1016/j.physe.2007.09.035
Abstract
We present a unified description of zitterbewegung-like phenomena for electron and hole systems showing Rashba spin splitting as well as for electrons in single-layer and bilayer graphene. The former class of systems can be interpreted as "nonrelativistic" whereas the latter are often called "ultrarelativistic" so that our unified description indicates an interesting connection between these two opposite limits.
