标题： Continuous Monitoring of Dynamical Systems and Master Equations

摘要： 我们说明由马尔可夫主方程描述的开放量子系统非幺正演化与涉及该系统的连续测量过程之间的等价性。 我们研究一个由两个耦合模式组成的系统，其中只有一个模式与外部自由度相互作用，第一种情况中由有限数量的谐振子表示，第二种情况中由一系列原子表示，每个原子在有限时间内与一个模式相互作用。 出现两种不同的模式，其中一种对应于大耗散极限下的类似Zeno行为。 显示英文摘要

摘要： We illustrate the equivalence between the non-unitary evolution of an open quantum system governed by a Markovian master equation and a process of continuous measurements involving this system. We investigate a system of two coupled modes, only one of them interacting with external degrees of freedom, represented, in the first case, by a finite number of harmonic oscillators, and, in the second, by a sequence of atoms where each one interacts with a single mode during a limited time. Two distinct regimes appear, one of them corresponding to a Zeno-like behavior in the limit of large dissipation.
