| Research Abstract |
We study edge states in topological superconductors and superfluids by solving the Eilenberger equation. We demonstrate that angular momentum by Cooper pairs in the superfluid helium-3 A-phase, which is a topological superfluid, has no relation to edge current because the edge current depends on the boundary condition at the edge strongly. We also demonstrate that UPt3 and PrOs4Sb12, which are topological superconductors, has Fermi arcs in edge states owing to point nodes of their gap functions.
