Description
I will present an introduction to the theory of quantum
link models, a.k.a. gauge magnets, that are particularly
suitable for realizations with ultracold atoms. These
models provide an alternative to the standard Wilson's
method formulation of lattice gauge theories (LGT).
I will derive the simplest Hamiltonian for Abelian U(1)
LGT and show the simplest SU(2) extension.
Implementation with Rydberg atoms will be shortly
discussed.
