Dyonic Sectors and Intertwiner Connections in 2+1-dimensional Lattice ZN-Higgs Models — •Florian Nill2 and Joao Carlos Alves Barata11Instituto de Física da Universidade de São Paulo, P.O. Box 66318, São Paulo 05315 970, SP, Brasil. — 2Inst. theor. Physik, FU-Berlin, Arnimallee 14, D-14195 Berlin

We construct dyonic states in 2+1-dimensional lattice ZN-Higgs models, i.e., states which are both, electrically and magnetically charged. The associated Hilbert spaces carry charged representations of the observable algebra, the global transfer matrix and a unitary implementation of the group of spatial lattice translations. We prove that for coinciding total charges these representations are dynamically equivalent and we construct a local intertwiner connection depending on a path in the space of charge distributions. The holonomy of this connection is given by ZN-valued phases. This will be the starting point for a construction of scattering states with anyon statistics in a subsequent paper.
