Lattice Background Effective Action: a Proposal
Paolo Cea🇮🇹 · Leonardo Cosmai🇮🇹
Abstract
We propose a method based on the Schrödinger 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.
