Dual simulation of the 2d U(1) gauge Higgs model at topological angle θ = π: Critical endpoint behavior
We simulate the 2d U(1) gauge Higgs model on the lattice with a topological angle θ. The corresponding complex action problem is overcome by using a dual representation based on the Villain action appropriately endowed with a θ-term. The Villain action is interpreted as a non-compact gauge theory wh...
