Zusammenfassung
Recent experiments have shown the potential of surface acoustic waves as a mean for transporting charge and spin in quantum wells. In particular, they have proven highly effective for the coherent transport of spin-polarized wave packets, suggesting their potential in spintronics applications.

Zusammenfassung
Recent experiments have shown the potential of surface acoustic waves as a mean for transporting charge and spin in quantum wells. In particular, they have proven highly effective for the coherent transport of spin-polarized wave packets, suggesting their potential in spintronics applications. Motivated by these experimental observations, the spin and charge dynamics in a quantum well under surface acoustic waves is theoretically studied. It is shown that the dynamics acquires a simple and transparent form in a reference frame co-moving with the surface acoustic wave. The results, e.g., the calculated spin relaxation and precession lengths, are in excellent agreement with recent experimental observations.
