Query: The ab initio study of unconventional superconductivity in CeCoIn$_{5}$
  and FeSe   Electronic structure and the shape of the Fermi surface are known to be of
fundamental importance for the superconducting instability in real materials.
We demonstrate that such an instability may be explored by static Cooper pair
susceptibility renormalized by pairing interaction and present an efficient
method of its evaluation using Wannier orbitals derived from ab initio
calculation. As an example, this approach is used to search for an
unconventional superconducting phase of the Fulde-Ferrell-Larkin-Ovchinnikov
(FFLO) type in a heavy-fermion compound CeCoIn$_5$ and an iron-based
superconductor FeSe. The results suggest that the FFLO superconducting phase
occurs at finite magnetic field in both materials.
