dc.descriptionIn this work we analyze an Aharonov-Bohm interferometer in the tunneling regime. In this regime, current magnification effect which arises in presence of transport currents is absent. A slight modification in the form of a quantum well incorporated in one of the arms leads to revival of current magnification. Systematics in magneto-conductance oscillations are observed in this evanescent wave geometry. In this framework we also see absence of Fano lineshapes in transmission resonances but once again one can recover these if the direct path supports propagating modes.
