Theory of Decoherence of Electron Waves - Visualizing the Quantum-Classical Transition — •Regine Frank — Institute for Theoretical Physics, Eberhard-Karls University Tübingen, Germany Center for Light-Matter-Interaction, Sensors and Analytics (LISA+) and Center for Complex Quantum Phenomena (CQ)

Controlled decoherence of free electrons due to Coulomb interaction with a truly macroscopic environment, a semiconducting plate, is studied theoretically using open quantum dynamics. The quantitative theoretical results are compared with experimental data. The comparison of theory and experiment confirms the main features of the theory of decoherence and can be interpreted in terms of which-path information which visualize the transition from quantum to classical.
