The Abelian Higgs model in 1 space and 1 time dimensions has important features in common with models relevant for high energy physics: confinement and existence of topological solutions of the classical equations of motion.

It is also one of the simplest model studied by lattice gauge theorists.  In the weak gauge coupling limit it reduces to the classical XY model which has a Kosterlitz-Thouless transition. I review the lattice gauge theory formulations of the model and describe recent proposals to implement this theory on optical lattices. I discuss recent progress regarding the entanglement entropy and the possibility of driving the system in a conformal (superfluid) phase.
