Nanorings asymmetrically connected to wires show different kinds of quantum interference phenomena under sudden excitations and in steady current conditions. Here, we contrast the transient current caused by an abrupt bias to the magnetic effects at constant current. A repulsive impurity can cause charge buildup in one of the arms and reverse current spikes. Moreover, it can cause transitions from laminar current flow to vortices, and also change the chirality of the vortex. The magnetic behavior of these devices is also very peculiar. Those nanocircuits, that consist of an odd number of atoms, behave in a fundamentally different manner compared to those that consist of an even number of atoms. The circuits having an odd number of sites con...
