Anisotropic electron-phonon coupling plus screened Coulomb repulsion on Weyl-semimetal Fermi arcs yields the observed nodal i-wave superconducting gap when the surface bandwidth matches the phonon energy scale.
Phonon-mediated intra-arc and inter-arc pairing in Fermi arcs of Weyl semimetals produces nodal surface superconductivity whose nodes arise from weak surface Coulomb screening.
Surface LPGE in Co3Sn2S2 shows magnetization-switchable sign reversals from unitary symmetries, with extrinsic parts large due to Fermi arcs and scaling as omega to the -2.2.
Point contacts on trigonal PtBi2 exhibit enhanced superconductivity with Tc up to 8 K, likely due to local strain from contact formation, observed with both normal and ferromagnetic tips and stronger at sample edges.

Point-contact enhanced superconductivity in trigonal PtBi2: quest for the origin of high-Tc
