Abstract
We evaluate the Polyakov loop and string tension at zero and finite temperature in QED2. Using bozonization the problem is reduced to solving the Schrödinger equation with a particular potential determined by the ground state. 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.
