Isotropic 3D f-wave topological Cooper pairing

ORAL

Abstract

We generalize the 3D isotropic p-wave spin triplet Cooper pairing state of the $^3$He-B type into even high orbital partial-wave channels with large-spin fermions. In the spin-3/2 case, the $f$-orbital partial wave channel can support a spin-septet pairing yielding a fully gapped rotationally invariant pairing structure. Its topological properties are analyzed through the calculation of the gapless surface spectra.
