Title: Spin-orbit interaction and novel shell structure for multi-electron system confined in 2D QD

By implementing Pauli’s spin-orbit (s/o) coupling and Darwin’s relativistic correction, we study how relativistic terms affect the Schrödinger picture of electrons in a 2D quantum dot (QD). The competition between electron confinement and Pauli’s s/o coupling produces a novel shell structure at Ω{sub 0} = 4mc{sup 2}/ħ, and the inclusion of these relativistic terms is strictly restricted in the Schrödinger picture to ω < Ω{sub 0}.
