Query: Local tunneling spectroscopy as signatures of the
  Fulde-Ferrell-Larkin-Ovchinnikov state in s- and d-wave Superconductors   The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states for two-dimensional s- and
d-wave superconductors (s- and d-SC) are self-consistently studied under an
in-plane magnetic field. While the stripe solution of the order parameter (OP)
is found to have lower free energy in s-SC, a square lattice solution appears
to be energetically more favorable in the case of d-SC. At certain symmetric
sites, we find that the features in the local density of states (LDOS) can be
ascribed to two types of bound states. We also show that the LDOS maps for d-SC
exhibit bias-energy-dependent checkerboard patterns. These characteristics can
serve as signatures of the FFLO states.
