In the presence of two sources of opposite charges the vacuum angle parameter $θ$ changes by $2π(q/e)$, independent of the number of flavors. This, in turn, alters the chiral condensate. Particularly, in the one flavor case through a simple computer algorithm, we explore the chiral dynamics of a heavy fermion.4 pages, 2 ps files, uses sprocl.sty.
