24 May 2004 | | Journal: | Phys. Rev. A 70 032113 (2004) (13 pages) | | Subject: | quant-ph | | Affiliation: | Univ. of KwaZulu-Natal, South Africa ENS, Paris, France Univ. of Palermo, Italy | | Abstract: | The dynamics of a typical open quantum system, namely a quantum Brownian particle in a harmonic potential, is studied focussing on its non-Markovian regime. Both an analytic approach and a stochastic wave function approach are used to describe the exact time evolution of the system. The border between two very different dynamical regimes, the Lindblad and non-Lindblad regimes, is identified and the relevant physical variables governing the passage from one regime to the other are singled out. The non-Markovian short time dynamics is studied in detail by looking at the mean energy, the squeezing, the Mandel parameter and the Wigner function of the system. | | Source: | arXiv, quant-ph/0405140 | | Services: | Forum | Review | PDF | Favorites | |
