Spin-orbit-enhanced Wigner localization in quantum dots
arXiv:1108.0512 · doi:10.1103/PhysRevB.84.235117
Abstract
We investigate quantum dots with Rashba spin-orbit coupling in the strongly-correlated regime. We show that the presence of the Rashba interaction enhances the Wigner localization in these systems, making it achievable for higher densities than those at which it is observed in Rashba-free quantum dots. Recurring shapes in the pair-correlated densities of the yrast spectrum, which might be associated with rotational and vibrational modes, are also reported.
