Abstract
We investigate the two-terminal electronic transport of a model mesoscopic ring threaded by a magnetic flux and embedded in between two semi-infinite metallic electrodes. The ring is locally distorted to bring a pair of atomic sites residing in the two opposite arms into close proximity. The proximity of the two atoms is modeled by an inter-arm tunnel hopping matrix element, and is shown to lead to nontrivial features in the transmission and the density of states of the system. The asymmetric Fano lineshape and its reversal, the Aharonov–Bohm oscillations in the conductance and the device aspect of the system are critically examined.
