论文摘要
分析和讨论了Caldeira-Leggett主方程中的一些未开发的破坏性方面。破裂过程由两个环境参数（弛豫速率或摩擦和温度）控制，从而导致从量子到经典状态的逐渐过渡。到达时间分布，非最小值 - 不确定性产品或拉伸高斯波数据包，相同的粒子和时间的衍射显示在时间依赖的干扰模式经历的变形过程中显示有趣的特征。我们表明，恒定力场的存在不会影响伸缩参数的{\ it阳性}值降低了反熔的速率，当考虑开放动力学时，相同粒子的波函数的对称性不起作用；通过在所谓的量子快门问题中增加温度和/或放松率，逐渐消除了时间和空间的衍射。
Some unexplored decoherence aspects within the Caldeira-Leggett master equation are analyzed and discussed. The decoherence process is controlled by the two environment parameters, the relaxation rate or friction and the temperature, leading to a gradual transition from the quantum to classical regime. Arrival time distributions, nonminimum-uncertainty-product or stretching Gaussian wave packets, identical particles and diffraction in time display interesting features during the decoherence process undergone by the time dependent interference patterns. We show that the presence of a constant force field does not affect the decoherence, {\it positive} values of the stretching parameter reduces the rate of decoherence, the symmetry of the wave function for identical particles plays no role when open dynamics are considered; and diffraction in time and space is gradually washed out by increasing the temperature and/or relaxation rate in the zero dissipation limit within the so-called quantum shutter problem.
