Exotic order in simple models of bosonic systems
arXiv:cond-mat/0205170 · doi:10.1103/PhysRevLett.89.277004
Abstract
We show that simple Bose Hubbard models with unfrustrated hopping and short range two-body repulsive interactions can support stable fractionalized phases in two and higher dimensions, and in zero magnetic field. The simplicity of the constructed models advances the possibility of a controlled experimental realization and novel applications of such unconventional states.
