Abstract
We show that the logarithmically rising static potential between opposite-c harged sources in two dimensions is screened by dynamical fields even if th e probe charges are fractional, in units of the charge of the dynamical fie lds. The effect is due to quantum mechanics: the wave functions of the scre ening charges are superpositions of two bumps localized both near the oppos ite- and the same-charge sources, so that each of them gets exactly screene d.
