Their non-Abe lian realizations are particularly relevant to topological quantum computa tion and quantum simulation. Our goal is to determine the general structur e of the phase diagrams of lattice gauge theories based on discrete non-Ab elian groups. We report recent advances in this direction. Exact diagonali zation reveals symmetry-protected degeneracies in the magnetic limit that match the anyon content of the corresponding quantum double models and app ear to persist away from this limit\, while the electric-limit spectrum is analysed using representation theory. In parallel\, we develop a Euclidea n Monte Carlo formulation to study larger systems and characterize the pha ses and transitions of these theories.

Lattice gauge theor ies describe gauge interactions in high-energy physics and emergent gauge structures in quantum matter. Their non-Abelian realizations are particula rly relevant to topological quantum computation and quantum simulation. Ou r goal is to determine the general structure of the phase diagrams of latt ice gauge theories based on discrete non-Abelian groups.

We repo rt recent advances in this direction. Exact diagonalization reveals symmet ry-protected degeneracies in the magnetic limit that match the anyon conte nt of the corresponding quantum double models and appear to persist away f rom this limit\, while the electric-limit spectrum is analysed using repre sentation theory. In parallel\, we develop a Euclidean Monte Carlo formula tion to study larger systems and characterize the phases and transitions o f these theories.
