Andreev bound states in non-centrosymmetric superconductors
We describe surface bound states (Andreev states) in superconductors without an inversion center. We show that the existence and the energy of these states are determined by the structure of the order parameter, and by the scattering between two helicity bands, which depends on the geometry of the spin-orbit field g (k), and the orientation of the surface. © 2007 Elsevier B.V.
