Matching Lagrangian and Hamiltonian Simulations in (2+1)-dimensional U(1) Gauge Theory

C. F. Groß, S. Romiti, L. Funcke +4

At finite lattice spacing, Lagrangian and Hamiltonian predictions differ due to discretization effects. In the Hamiltonian limit, i.e. at vanishing temporal lattice spacing $a_t$,…
