Topological superconductivity in superconducting chiral topological semimetals with parallel spin-momentum locking
The study investigates intrinsic unconventional superconductivity in chiral topological semimetals using a cubic lattice model. It found that parallel spin-momentum locking favors zero-momentum intranode pairing, leading to distinct first-order and second-order topological superconducting phases based on the interplay between s± and d+id pairing symmetries.
