Exploring the Unstable Modes Dynamics by the Lattice Schrodinger Functional

High Energy Physics - Lattice 2009-10-28 v1

Abstract

We analyze the problem of the Nielsen-Olesen unstable modes in the SU(2)SU(2) lattice gauge theory by means of a recently introduced gauge-invariant effective action. We perform numerical simulations in the case of a constant Abelian chromomagnetic field. We find that for lattice sizes above a certain critical length the density of effective action shows a behaviour compatible with the presence of the unstable modes.
