Query: Numerical simulation of self-dual U(1) lattice field theory with
  electric and magnetic matter   We study a recently proposed formulation of U(1) lattice field theory with
electric and magnetic matter based on the Villain formulation. This
discretization allows for a duality that gives rise to relations between weak
and strong gauge coupling. There exists a self-dual value of the gauge coupling
where one may study the model as a function of the remaining matter coupling.
Using Monte Carlo simulations based on a worldline/worldsheet representation of
the system we evaluate order parameters for spontaneous breaking of
self-duality. We find that in some interval of the matter coupling self-duality
becomes broken spontaneously. We determine the endpoints of this interval and
study the nature of the corresponding critical points. Finally we explore the
system away from the self-dual gauge coupling and show that when crossing the
self-dual point a first order jump is seen in the order parameters.
