Query: Berry phases, current lattices, and suppression of phase transitions in
  a lattice gauge theory of quantum antiferromagnets   We consider a lattice model of two complex scalar matter fields $z_{a},
a=1,2$ under a CP1 constraint $\abs{z_1}^2+\abs{z_2}^2=1$, minimally coupled to
a compact gauge field, with an additional Berry phase term. This model has been
the point of origin for a large body of works addressing novel paradigms for
quantum criticality, in particular spin-quark (spinon) deconfinement in S=1/2
quantum antiferromagnets. We map the model exactly to a link-current model,
which permits the use of classical worm algorithms to study the model in
large-scale Monte Carlo simulations on lattices of size L^3, up to L=360. We
show that the addition of a Berry phase term to the lattice $\CP$-model
suppresses the phase transition in the $\groupO{3}$ universality class of the
$\CP$-model. The link-current formulation of the model is useful in identifying
the mechanism by which the phase transition is suppressed.
