Theory of the topological Anderson insulator
... spin. We assume time reversal symmetry (no magnetic field or magnetic impurities) and neglect any coupling between the two spin blocks H and H ∗ [9]. The scalar potential U accounts for the disorder. The parameters α, β, γ, m depend on the thickness and composition of the quantum well [7]. For the s ...
