受驱动开放量子系统中的涨落定理

Fluctuation theorems in driven open quantum systems

Peter Talkner, Michele Campisi, Peter Hänggi

摘要:

导出了量子系统在外力作用下两个对易观测量变化的联合测量的特征函数。特别地,一个{ \it}与其环境弱耦合的量子系统的内能、交换热和功的统计是根据由于经典的外力作用于系统而引起的系统和环境的能量变化来确定的。如果系统和环境最初是在一个典型的平衡,系统上进行的工作,满足Tasaki-Crooks定理和Jarzynski等式。

英文摘要:

The characteristic function for the joint measurement of the changes of two commuting observables upon an external forcing of a quantum system is derived. In particular, the statistics of the internal energy, the exchanged heat and the work of a quantum system that {\it weakly} couples to its environment is determined in terms of the energy changes of the system and the environment due to the action of a classical, external force on the system. If the system and environment initially are in a canonical equilibrium, the work performed on the system is shown to satisfy the Tasaki-Crooks theorem and the Jarzynski equality.
