Abstract:
We investigate the non-interacting 2D Anderson model with Rashba type spin-orbit coupling
over the localized-delocalized phase transition. We calculate a coarse-grained picture of the
disorder strength - SOC coupling strength phase diagram. We also investigate the persistence
of information about the initial state through imbalance measurements. We compare the
imbalance retention for different densities such as charge density, Si for different initial
conditions. We show that the charge and spin imbalances behave in qualitatively different
ways as we move through the parameter space. The spin imbalance is less robust than the
charge imbalance for small spin-orbit coupling but more robust at large coupling values. The
dependence of the charge imbalance on the presence/absence of a spin pattern in the initial
condition is also investigated.
