Interpolated Lattice Gauge Fields and Chiral Fermions in the Schwinger Model
Abstract
Description
The effective action induced by fermions in the chiral Schwinger model with charges (3,4,5) is investigated. Pauli-Villars regularization is combined with momentum cut-off for the evaluation of the fermion determinants on continuum gauge fields interpolated between lattice points. The convergence and gauge variance are studied numerically on gauge configurations taken from quenched updating.
