Superconducting 2D System with Lifted Spin Degeneracy: Mixed Singlet-Triplet State
Superconducting 2D System with Lifted Spin Degeneracy: Mixed Singlet-Triplet State
Motivated by recent experimental findings, we have developed a theory of the superconducting state for 2D metals without inversion symmetry modeling the geometry of a surface superconducting layer in a field-effect-transistor or near the boundary doped by adsorbed ions. In such systems the two-fold spin degeneracy is lifted by spin-orbit …
