Bouncing transient currents and SQUID-like voltage in nanodevices at half filling
Bouncing transient currents and SQUID-like voltage in nanodevices at half filling
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 …
