摘要：

It is shown recently triplet superconductors like Sr2RuO4, UPt3 and PrOs4Sb12 have Majorana fermion, d-soliton and half-quantum vortices (HQVs). The Bogoliubov de Gennes (BdG) equation necessary for the present purpose is derived following Ivanov. For H Pc and d-vector in the ab plane the one of HQVs has a series of bound states including the zero-energy-mode or Majorana fermion while the other has no bound state for a single spin component. We illustrate this for p-wave SC.
