Abstract
We study theoretically the stability of persistent spin helix in two-dimensional electron gases with spin-orbit coupling by a semi-classical spin density matrix method. The possible influences of disordering scattering, temperature, spin-orbit coupling strength and external electric field on the lifetime of persistent spin helix state are investigated. The theoretical results are found to be in agreement with some recent relevant experimental results.
