    "abstract": "The dynamics of a typical open quantum system, namely a quantum Brownian\nparticle in a harmonic potential, is studied focussing on its non-Markovian\nregime. Both an analytic approach and a stochastic wave function approach are\nused to describe the exact time evolution of the system. The border between two\nvery different dynamical regimes, the Lindblad and non-Lindblad regimes, is\nidentified and the relevant physical variables governing the passage from one\nregime to the other are singled out. The non-Markovian short time dynamics is\nstudied in detail by looking at the mean energy, the squeezing, the Mandel\nparameter and the Wigner function of the system.",
