We find that the pseudospin plays a key role in the structure of the pairing amplitude. An attractive on-site interaction leads to pairing between quasiparticles carrying opposite spin and opposite topological charge, resulting in the formation of real-spin singlet pairs that are a mixture of pseudospin singlet and pseudospin triplet. Our results provide a detailed characterization of the exotic pairing behavior in this system, and they represent an important step toward a more complete understanding of superconductivity in the context of topological band structures, which will help guide searches for topological superconductivity in real materials and ultracold atoms. © 2019 American Physical Society.", title = "Numerically exact study of Weyl superconductivity", doi = "10.1103/PHYSREVB.100.104522" }
