The (2 + 1)-d U (1) quantum link model is a gauge theory, amenable to quantum simulation, with a spontaneously broken S O (2) symmetry emerging at a quantum phase transition. Its low-energy physics is described by a (2 + 1)-d R P (1) effective field theory, perturbed by an S O (2) breaking operator, which prevents the interpretation of the emergent pseudo-Goldstone boson as a dual photon. At the quantum phase transition, the model mimics some features of deconfined quantum criticality, but remains linearly confining. Deconfinement only sets in at high temperature.
