Controlled electron transport in coupled Aharonov-Bohm rings
Supriya Jana, Arunava Chakrabarti
We propose a simple model of two coupled mesoscopic rings threaded by magnetic flux which mimics a device for electron transmission in a controlled fashion. Within a tight binding…

Electronic transmission in bent quantum wires
Arunava Chakrabarti
Electronic transmission in bent quantum wires modeled by the tight binding Hamiltonian, and clamped between ideal, semi-infinite leads is studied. The effect of `bending' the chain…

Flux induced semiconducting behavior of a quantum network
Shreekantha Sil, Santanu K. Maiti, Arunava Chakrabarti
We show that a diamond shaped periodic network, recently proposed as a model of a spin filter (A. Aharony {\em et al.} \cite{aharon08}) is capable of behaving as a p-type or an n-t…
