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…
