Query: Paramagnetic properties of non-centrosymmetric superconductors:
  Application to CePt3Si   In a non-centrosymmetric crystal, the Zeeman interaction of the band
electrons with an external magnetic field is highly anisotropic in the momentum
space, vanishing along some high-symmetry planes. One of the consequences is
that the paramagnetic susceptibility in superconductors without inversion
symmetry, such as CePt3Si, shows an unusual temperature dependence.
