Decoherence in ballistic mesoscopic interferometers
Georg Seelig, Sebastian Pilgram, Markus Buttiker
We provide a theoretical explanation for two recent experiments on decoherence of Aharonov-Bohm oscillations in two- and multi-terminal ballistic rings. We consider decoherence due…
Probe-configuration dependent dephasing in a mesoscopic interferometer
G. Seelig, S. Pilgram, A. N. Jordan +1
Dephasing in a ballistic four-terminal Aharonov-Bohm geometry due to charge and voltage fluctuations is investigated. Treating two terminals as voltage probes, we find a strong dep…
Electron-phonon scattering in quantum point contacts
Georg Seelig, K. A. Matveev
We study the negative correction to the quantized value of the conductance of a quantum point contact due to the backscattering of electrons by acoustic phonons. The corre…
Capacitance of a quantum dot from the channel-anisotropic two-channel Kondo model
Karyn Le Hur, Georg Seelig
We investigate the charge fluctuations of a large quantum dot coupled to a two-dimensional electron gas via a quantum point contact following the work of Matveev. We limit our disc…
Charge fluctuation induced dephasing in a gated mesoscopic interferometer
Georg Seelig, Markus Buttiker
The reduction of the amplitude of Aharonov-Bohm oscillations in a ballistic one-channel mesoscopic interferometer due to charge fluctuations is investigated. In the arrangement con…
Spin interactions and switching in vertically tunnel-coupled quantum dots
Guido Burkard, Georg Seelig, Daniel Loss
We determine the spin exchange coupling J between two electrons located in two vertically tunnel-coupled quantum dots, and its variation when magnetic (B) and electric (E) fields (…
