Vortex in chiral superconducting state

We have investigated the vortex in chiral superconductors, especially in p- wave case. In chiral superconductors the Cooper pair has orbital angular mo mentum hence U(1), parity (P) and time reversal symmetry (T) are broken sim ultaneously. We have found that the vortex has fractional charge and fracti onal angular momentum which comes from P- and T-violation. The fractionaliz ation of the angular momentum suggests that the vortex could be an anyon wh ich obeys the fractional statistics. We have also pointed out that the elec tric field is induced near the vortex core and non-trivial electromagnetic phenomena are expected to occur.
