Strolling along gauge theory vacua
We consider classical, pure Yang-Mills theory in a box. We show how a set of
static electric fields that solve the theory in an adiabatic limit correspond
to geodesic motion on the space of vacua, equipped with a particular Riemannian
metric that we identify. The vacua are generated by spontaneously broken global
gauge symmetries, leading to an infinite number of conserved momenta of the
geodesic motion. We show that these correspond to the soft multipole charges of
Yang-Mills theory.Comment: 46 pages, 1 figure, Published versio
