New proposal for including dynamical fermions in lattice gauge theories: The compact-QED case

We present a new method for including dynamical fermions in lattice gauge theories that can increase the efficiency of Monte Carlo simulations by significantly decreasing the amount of required computer time. The accuracy of the method is demonstrated by comparison with numerical results obtained with other methods in compact QED. New results on the phase transition of QED with massless fermions on $6^4$ and $8^4$ lattices are also presented.
