Rashba type spin-orbit coupling breaks inversion and spin symmetry, which can lead to a mixing of superconducting spin-singlet and spin-triplet states. Here, the authors present a numerical investigation of superconducting phases of the Rashba-Hubbard model. They study the two-dimensional square lattice as a paradigm and discuss how the arising superconducting phases, including helical spin-triplet condensates, emerge in detail and how to deal with them within a method which restricts paired electrons to momenta on the Fermi surface.
