Query: Correlation-enhanced odd-parity inter-orbital singlet pairing in the
  iron-pnictide superconductor LiFeAs   The rich variety of iron-based superconductors and their complex electronic
structure lead to a wide range of possibilities for gap symmetry and pairing
components. Here we solve in the 2-Fe Brillouin zone the full
frequency-dependent linearized Eliashberg equations for LiFeAs with
spin-fluctuation mediated pairing interactions. The magnetic excitations are
calculated with the random phase approximation on a correlated electronic
structure obtained with density functional theory and dynamical mean field
theory. Correlations induce long-lived local moments with orbital-dependent
dynamics. The interaction between electrons through Hund's coupling promotes
inter-orbital magnetic susceptibility. As a consequence, the leading pairing
channel, conventional $s^{+-}$, acquires sizeable inter-orbital
$d_{xy}-d_{xz(yz)}$ singlet pairing with odd parity under glide-plane symmetry.
These components reduce the superconducting gap magnitude induced by the
intra-orbital components of the gap function at the electron pockets
intersection where the Fe-d $t_{2g}$ orbitals strongly mix. This in turn makes
the results consistent with available experiments on the angular dependence of
the gaps observed on the different Fermi surfaces.
