We explore two flavor scalar electrodynamics on the lattice, which has acomplex phase problem at finite chemical potential. By rewriting the action interms of dual variables this complex phase problem can be solved exactly. Thedual variables are link- and plaquette occupation numbers, subject to localconstraints that have to be respected by the Monte Carlo algorithm. For thesimulation we use a local update as well as the newly developed "surface wormalgorithm", which is a generalization of the Prokof'ev Svistunov worm algorithmconcept for simulating the dual representation of abelian Gauge-Higgs models ona lattice. We assess the performance of the two algorithms, present results forthe phase diagram and discuss condensation phenomena.
