Description
We present a mapping of a two-dimensional system of interacting bosons in a strong perpendicular magnetic eld to an equivalent system of interacting bosons on the square lattice in the absence of the eld. The mapping utilizes a magnetic Bloch and the corresponding magnetic Wannier singleparticle basis in the lowest Landau level. By construction, the ground states of the resulting model of interacting bosons on the square lattice are gapped fractionalized liquids or gapless Bose metal states with broken time reversal symmetry at specic rational lling fractions.
