| 英文摘要 | We theoretically study the spatial behaviors of the spin precession in a two-dimensional electron system with spin-orbit interaction. through analysis of interaction between the spin and the effective magnetic field in the system, we obtain the general conditions to generate a persistent spin helix and predict a persistent spin helix pattern in [001]-grown quantum wells. particularly, we demonstrate that the phase of spin can be locked to propagate in a quantum well with su(2) symmetry. |
