Coherent Propagation of Spin Helices in a Quantum-Well Confined Electron Gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
We use phase-resolved transient grating spectroscopy to measure the propagation of spin helices in a high mobility -GaAs/AlGaAs quantum well with an applied in-plane electric fi…

Doppler velocimetry of spin propagation in a two-dimensional electron gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
Controlling the flow of electrons by manipulation of their spin is a key to the development of spin-based electronics. While recent demonstrations of electrical-gate control in spi…

Random walk approach to spin dynamics in a two-dimensional electron gas with spin-orbit coupling
Luyi Yang, J. Orenstein, Dung-Hai Lee
We introduce and solve a semi-classical random walk (RW) model that describes the dynamics of spin polarization waves in zinc-blende semiconductor quantum wells. We derive the disp…
