Query: Dual simulation of finite density lattice QED at large mass   We discuss a mapping of lattice QED with two flavors and a chemical potential
to dual variables, which are surfaces for the gauge fields and loops for the
fermions. The gauge fields are completely dualized and the corresponding dual
variables are integer valued plaquette occupation numbers with constraints that
lead to a structure of surfaces that are either closed or bounded by fermion
loops. The fermion loops are obtained from a resummed hopping expansion (large
mass expansion) of the determinant of the Wilson-Dirac operator. The loops can
come with both positive and negative signs. We identify a sub-class of loops,
which we refer to as quasi-planar loops, where the total sign is positive. For
this sub-class a dual Monte Carlo simulation is possible and we discuss its
implementation and some results. In particular we address condensation
phenomena at finite chemical potential.
