Fermion bag approach to the sign problem in strongly coupled lattice QED with Wilson fermions

Preprint English OPEN
Chandrasekharan, Shailesh; Li, Anyi;

We explore the sign problem in strongly coupled lattice QED with one flavor of Wilson fermions in four dimensions using the fermion bag formulation. We construct rules to compute the weight of a fermion bag and show that even though the fermions are confined into bosons... View more
