| Abstract: | We put forward a toy model for a “bubble chamber” and study its interaction with an incoming object particle. We discuss the notion of particle “tracks” inside the bubble chamber and analyze the mechanisms that provoke a loss of quantum mechanical coherence (decoherence). The model is solvable and provides interesting insights into some of the most salient features of the interaction between a microscopic particle and a macroscopic device. |
