Description
Summary:We briefly review the present status of our phenomenological study of superconductivity in non-centrosymmetric materials, with a strong focus on CePt3Si. The Anderson theorems are examined in the context of antisymmetric spin-orbit coupling. Then the behavior of superconductivity in high magnetic fields is discussed in particular in view of paramagnetic limiting and the presence of a so-called helical phase. Finally, various experimental data are discussed in order to identify the pairing symmetry as a parity-mixed 's-wave' phase.
