Real quantum systems can exhibit a local object called local partial density of states (LPDOS) that cannot be proven within the axiomatic approach of quantum mechanics. We demonstrate that real mesoscopic system that can exhibit Fano resonances will show this object and, quite counterintuitively, it can become negative, resulting in the enhancement of coherent currents.
