Spin and charge dynamics
The spin and charge dynamics in a quantum well under surface acoustic waves has been studied by J. Wanner et al. In particular, a simple and transparent form of the dynamics is found in a co-moving reference frame. The calculated spin relaxation and precession lengths agree well with recent experimental observations. [
