Theory of 'which path' dephasing in single electron interference due to trace in conductive environment
arXiv:quant-ph/0511022 · doi:10.1103/PhysRevB.73.155109
Abstract
A single-electron two-path interference (Young) experiment is considered theoretically. The decoherence of an electron wave packet due to the 'which path' trace left in the conducting (metallic) plate placed under the electron trajectories is calculated using the many-body quantum description of the electron gas reservoir.
