We derive an exact representation of the massless Schwinger model on the lattice in terms of dual variables which are configurations of loops, dimers and plaquette occupation numbers. When expressed with the dual variables the partition sum has only real and positive terms also when a chemical potential or a topological term are added -- situations where the conventional representation has a complex action problem. The dual representation allows for Monte Carlo simulations without restrictions on the values of the chemical potential or the vacuum angle.

Grassmann Tensor Renormalization Group for two-flavor massive Schwinger model with a theta term
A Grassmann TRG calculation of the Nf=2 massive Schwinger model finds 2pi-periodic free energy that matches large-mass analytics and suggests finite-beta deviations from the continuum phase structure.
