Query: Spin Susceptibility in Non-centrosymmetric Superconductors with
  Topological Transition of Fermi Surfaces   The non-centrosymmetric superconductors Li2Pd3B and Li2Pt3B show different
superconducting properties despite having the same crystal symmetry. Motivated
by experimental results, we investigate the spin susceptibility of
non-centrosymmetric superconductors accompanied by the topological transition
of Fermi surfaces due to antisymmetric spin-orbit coupling, which is indicated
by the first-principles band structure calculation for Li2Pt3B. We study three
types of topological transition, namely, (A) the disappearance of the Fermi
surface, (B) crossing the Dirac point, and (C) crossing the saddle point
van-Hove singularity. The spin susceptibility in the superconducting state is
increased by the topological transitions (A) and (C), while it is decreased by
(B). We discuss the unusual magnetic properties observed in Li2Pt3B on the
basis of these results.
