Query: Quantum phase transitions from competing short- and long-range
  interactions on a $\pi$-flux lattice   Quantum phase transitions from the cluster-charge interaction, which is
composed of competing short- and long-range interactions, are investigated on a
$\pi$-flux lattice by using the mean-field theory and determinant quantum Monte
Carlo (DQMC) simulations. Both methods identify a plaquette-dimer phase, which
develops from a finite interaction strength. While its signature in DQMC is
relatively weak, a obvious antiferromagnetic transition is revealed in the spin
structure factor instead. The corresponding critical interaction and exponents
are readily obtained by finite-size scalings, with the plaquette-dimer
structure factor that can also be well scaled. These results suggest a possible
deconfined quantum critical point between the plaquette-dimer and
antiferromagnetic phases driven by the cluster-charge interaction on a
$\pi$-flux lattice.
