Magnetotransport in a double quantum wire | Vidar Gudmundsson

19 Jun 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect | Abstract: | We model electronic transport through a double quantum wire in an external homogeneous perpendicular magnetic field using a scattering formalism built on the Lippmann-Schwinger equation. In the scattering region a window is opened between the parallel wires allowing for inter- and intra-wire scattering processes. Due to the parity breaking of the magnetic field the ensuing subband energy spectrum of the double wire system with its regimes of hole- and electron-like propagating modes leads to a more structure rich conductance as a function of the energy of the incoming waves than is seen in a single parabolically confined quantum wire. The more complex structure of the evanescent modes of the system also leaves its marks on the conductance. | Source: | arXiv, cond-mat/0606480 | Services: | Forum | Review | PDF | Favorites |
