Lattice Background Effective Action: a Proposal

High Energy Physics - Lattice 2009-10-28 v1

Abstract

We propose a method based on the Schr\"odinger functional for computing on the lattice the gauge invariant effective action for external background fields. We check this method by studying the U(1) lattice gauge theory in presence of a constant magnetic background field.
