    "abstract": "We introduce a model for a two configurations system, and we study the\ntransition from quantum to classical behaviour. We first consider the effect of\nthe interaction with the environment as an external noise and we show that it\nproduces decoherence and suppression of tunnelling. These features are widely\naccepted as definition of classicality, while we believe that classicality\nimplies that quantum delocalized states spontaneously evolve into localized\nones. We than show that this evolution take place only when both noise and non\nlinearity in the equations are present.",
