We implement a Chern-Simons (CS) contribution into the compact QED<Subscript>3</Subscript> description of the antiferromagnetic Heisenberg model in two dimensions at zero temperature. The CS term allows for the conservation of the SU(2) symmetry of the quantum spin system and fixes the flux through a plaquette to be a...</subscript>
