Abstract
Bosonic model with unfrustrated hopping and short-range repulsive interaction is constructed that realizes fractionalized insulator phase in two dimensions and in zero magnetic field. Such phase is characterized as having gapped charged excitations that carry fractional electrical charge 1/3 and also gapped vortices above the topologically ordered ground state.
