Their non-Ab elian realizations are particularly relevant to topological quantum comput ation and quantum simulation. Our goal is to determine the general structu re of the phase diagrams of lattice gauge theories based on discrete non-A belian groups. We report recent advances in this direction. Exact diagonal ization reveals symmetry-protected degeneracies in the magnetic limit that match the anyon content of the corresponding quantum double models and ap pear to persist away from this limit\, while the electric-limit spectrum i s analysed using representation theory. In parallel\, we develop a Euclide an Monte Carlo formulation to study larger systems and characterize the ph ases and transitions of these theories.

Lattice gauge theo ries describe gauge interactions in high-energy physics and emergent gauge structures in quantum matter. Their non-Abelian realizations are particul arly relevant to topological quantum computation and quantum simulation. O ur goal is to determine the general structure of the phase diagrams of lat tice gauge theories based on discrete non-Abelian groups.

We rep ort recent advances in this direction. Exact diagonalization reveals symme try-protected degeneracies in the magnetic limit that match the anyon cont ent of the corresponding quantum double models and appear to persist away from this limit\, while the electric-limit spectrum is analysed using repr esentation theory. In parallel\, we develop a Euclidean Monte Carlo formul ation to study larger systems and characterize the phases and transitions of these theories.
