建立了Lévy过程的特征函数与描述量子系统通过动量转移事件与环境相互作用的质心自由度的统计算子的相干性损失之间的一般联系。与微物理模型和最近的实验的关系被认为是，专注于最近观察到的复合泊松过程和高斯过程描述的动态之间的过渡。
A general connection between the characteristic function of a Lévy process and loss of coherence of the statistical operator describing the center of mass degrees of freedom of a quantum system interacting through momentum transfer events with an environment is established. The relationship with microphysical models and recent experiments is considered, focusing on the recently observed transition between a dynamics described by a compound Poisson process and a Gaussian process.
