 abstract = {Motivated by experiments on Josephson junction arrays in a magnetic
field and ultracold interacting atoms in an optical lattice in the
presence of a ``synthetic″ orbital magnetic field, we study the
``fully frustrated″ Bose-Hubbard model and quantum XY model with half
a flux quantum per lattice plaquette. Using Monte Carlo simulations and
the density matrix renormalization group method, we show that these
kinetically frustrated boson models admit three phases at integer
filling: a weakly interacting chiral superfluid phase with staggered
loop currents which spontaneously break time-reversal symmetry, a
conventional Mott insulator at strong coupling, and a remarkable
``chiral Mott insulator″ (CMI) with staggered loop currents
sandwiched between them at intermediate correlation. We discuss how the
CMI state may be viewed as an exciton condensate or a vortex supersolid,
study a Jastrow variational wave function which captures its
correlations, present results for the boson momentum distribution across
the phase diagram, and consider various experimental implications of our
phase diagram. Finally, we consider generalizations to a staggered flux
Bose-Hubbard model and a two-dimensional (2D) version of the CMI in
weakly coupled ladders.},
