Description
We study U(1) lattice field theory in the Villain formulation and couple electrically as well as magnetically charged bosonic matter. The system has a manifest self-duality that allows to establish a relation between the weak and strong coupling regimes. The complex action problem can be overcome with a worldline representation such that numerical simulations are possible. We study the spontaneous breaking of self-duality and present results for the phase diagram.
