Driven Dirac-like Equation via Mirror Oscillation: Controlled Cold-Atom Zitterbewegung
arXiv:1003.3074 · doi:10.1103/PhysRevA.81.023608
Abstract
By considering mirror oscillation in a "tripod-scheme" laser-atom system, we advocate explorative studies of driven Dirac-like equations. Both analytical and numerical studies show that mirror oscillation can be used to drive an effective spin-orbit interaction and hence control the amplitude, the frequency, and the damping of the cold-atom Zitterbewegung oscillation. Our results demonstrate an interesting coupling between the mirror mechanical motion and a fundamental quantum coherent oscillation, opening up new means of matter wave manipulation.
