Visibility fringe reduction due to noise-induced effects: Microscopic approach to interference experiments

Decoherence is the main process behind the quantum to classical transition. It is a purely quantum mechanical effect by which the system loses its ability to exhibit coherent behavior. The recent experimental observation of diffraction and interference patterns for large molecules raises some intere...
