                         solutions of the effective 4x4 Dimmock k\⋅p model, which 
                         gives an accurate description of the bands around the fundamental 
                         energy gap. Specific results for three-layer Pb1\−xSnxTe 
                         nanostructures with varying Sn composition are presented and the 
                         main differences between topological and normal (N) QWs 
                         highlighted. A series of new features are found in the spectrum of 
                         T-QWs, in particular in asymmetric QWs where large (Rashba 
                         spinorbit) splittings are obtained for the topological Dirac 
                         states inside the gap.",
