Finding exotic superconducting pairing in topological semimetals
ORAL
Abstract
We explore the possibility of exotic superconducting pairing in topological semimetals. The topology and the associated symmetries of the semimetals result in a unique electronic band structure, which affects the superconducting gap structure and pair amplitude. In addition to the conventional spin-singlet even-frequency pairing it is possible to find odd-frequency spin-triplet pairing and also pairing with higher intrinsic angular momentum. We also investigate possible experimental probes which can distinguish the signatures of the exotic pairing.
