# Symmetry, nodal structure, and Bogoliubov Fermi surfaces for nonlocal pairing

@article{Timm2021SymmetryNS, title={Symmetry, nodal structure, and Bogoliubov Fermi surfaces for nonlocal pairing}, author={Carsten Timm and Ankita Bhattacharya}, journal={Physical Review B}, year={2021} }

Multiband effects can lead to fundamentally different electronic behavior of solids, as exemplified by the possible emergence of Fermi surfaces of Bogoliubov quasiparticles in centrosymmetric superconductors which break time-reversal symmetry. We extend the analysis of possible pairing symmetries, the corresponding nodal structure, and the Bogoliubov Fermi surfaces in two directions: We include nonlocal pairing and we consider internal degrees of freedom other than the effective angular…

It is shown that, for an even-parity nodal superconducting state which spontaneously breaks time-reversal symmetry, the low-energy excitation spectrum generally does not belong to any of these categories and has extended Bogoliubov Fermi surfaces, which are topologically protected from being gapped by a Z_{2} invariant.

It is shown that pairing occurs between j=3/2 fermion states, which leads to qualitative differences from the conventional theory of pairing, which permits Cooper pairs with quintet or septet total angular momentum, in addition to the usual singlet and triplet states.
