Interaction-Induced Quantum Dephasing in Mesoscopic Rings
Abstract
Combining nonperturbative techniques with Monte Carlo simulations we demonstrate that quantum coherence effects for a particle on a ring are suppressed beyond a finite length Lφ even at zero temperature if the particle is coupled to a diffusive electron gas by means of long range Coulomb interaction. This length is consistent with Lφ derived from weak-localization-type of analysis.
