# Lattice Abelian-Higgs model with noncompact gauge fields

@article{Bonati2021LatticeAM, title={Lattice Abelian-Higgs model with noncompact gauge fields}, author={Claudio Bonati and Andrea Pelissetto and Ettore Vicari}, journal={Physical Review B}, year={2021} }

We consider a noncompact lattice formulation of the three-dimensional electrodynamics with $N$-component complex scalar fields, i.e., the lattice Abelian-Higgs model with noncompact gauge fields. For any $N\ensuremath{\ge}2$, the phase diagram shows three phases differing for the behavior of the scalar-field and gauge-field correlations: The Coulomb phase (short-ranged scalar and long-ranged gauge correlations), the Higgs phase (condensed scalar-field and gapped gauge correlations), and the…

It is argued that the phase diagram of higher-charge models presents three different phases, related to the condensation of gauge-invariant bilinear scalar fields breaking the global SU(N) symmetry, and to the confinement and deconfinement of external charge-one particles.
