Query: Influence of electron-phonon coupling strength on signatures of even and
  odd-frequency superconductivity   The recently discovered APt$_3$P (A=Sr,Ca,La) family of superconductors
offers a platform to study frequency dependent superconducting phenomena as the
electron-phonon coupling varies from weak to strong. Here we perform ab initio
Eliashberg theory calculations to investigate two such phenomena, the
occurrence of dip-hump structures in the tunneling spectra and the magnetic
field induced coexistence of even and odd frequency superconductivity in these
compounds. By calculating the superfluid density, we make predictions for the
occurrence of the paramagnetic Meissner effect as a hallmark of odd frequency
pairing. Our results provide a link between two seemingly uncorrelated aspects
of even and odd frequency superconductivity and provide theoretical guidance
for the experimental identification of bulk odd frequency superconductivity in
this material's family.
