Collective coordinate quantization of $C{P}^1$ model coupled to Hopf term revisited

Abstract

We show that the system where $C{P}^1$ model coupled to Hopf term can reveal fractional spin in a collective coordinate quantization scheme, provided one makes a transition to physically inequivalent sector within a same solitonic sector characterized by a nonvanishing topological number
