RESUMO
We consider the gauge potential A and argue that the minimum value of the volume integral of A2 (in Euclidean space) may have physical meaning, particularly in connection with the existence of topological structures. A lattice simulation comparing compact and noncompact "photodynamics" shows a jump in this quantity at the phase transition, supporting this idea.
