Cooper pairs with broken parity and spin-rotational symmetries in d-wave superconductors

Paramagnetic effects are shown to result in the appearance of a triplet component of order parameter in a vortex phase of a -wave superconductor in the absence of impurities. This component, which breaks parity and spin-rotational symmetries of Cooper pairs, is expected to be of the order of unity i...

Description
Summary:Paramagnetic effects are shown to result in the appearance of a triplet component of order parameter in a vortex phase of a -wave superconductor in the absence of impurities. This component, which breaks parity and spin-rotational symmetries of Cooper pairs, is expected to be of the order of unity in a number of modern superconductors such as organic, high Tc, and some others. A generic phase diagram of such type-IV superconductors, which are singlet ones at H=0 and in the Meissner phase, and characterized by singlet-triplet mixed Copper pairs Deltas+iDeltat with broken symmetries in a vortex phase, is discussed.
