Tuning of coupling modes in laterally parallel double open quantum dots
Chi-Shung Tang, Wing Wa Yu, Vidar Gudmundsson
We consider electronic transport through laterally parallel double open quantum dots embedded in a quantum wire in a perpendicular magnetic field. The coupling modes of the dots ar…
A state with negative binding energy induced by coherent transport in a quantum wire
Vidar Gudmundsson, Chi-Shung Tang, Andrei Manolescu
In a two-dimensional quantum wire in a perpendicular magnetic field with a smooth embedded repulsive scattering potential we find in the multimode conductance resonances caused by…
The Fano regime of one-dot Aharonov-Bohm interferometers
Valeriu Moldoveanu, Mugurel Ţolea, Vidar Gudmundsson +1
We use the Landauer-Büttiker formalism to study the mesoscopic Fano effect in Aharonov-Bohm rings with an embedded two-dimensional noninteracting dot. The magnetic field dependence…
