%0 Journal Article %T Quantum systems with time-dependent boundaries %A Sara Di Martino %A Paolo Facchi %J Physics %D 2015 %I arXiv %R 10.1142/S0219887815600038 %X We present here a set of lecture notes on quantum systems with time-dependent boundaries. In particular, we analyze the dynamics of a non-relativistic particle in a bounded domain of physical space, when the boundaries are moving or changing. In all cases, unitarity is preserved and the change of boundaries does not introduce any decoherence in the system. %U http://arxiv.org/abs/1501.06490v1
