两个量子系统之间的热平衡

Thermal equilibration between two quantum systems

Alexey V. Ponomarev, Sergey Denisov, Peter Hänggi

摘要:

两个完全相同的有限量子系统,最初在不同的温度下制备,从环境中隔离,随后进入接触被证明向吉布斯类准平衡态松弛与一个共同的温度和周围的一般观测值的时间平均期望值的小波动。时间热化过程通过一系列类似吉布斯的中间态进行。我们指定的条件下,这种情况发生,并证实了量子平衡与两种不同的模型。

英文摘要:

Two identical finite quantum systems prepared initially at different temperatures, isolated from the environment, and subsequently brought into contact are demonstrated to relax towards Gibbs-like quasi-equilibrium states with a common temperature and small fluctuations around the time-averaged expectation values of generic observables. The temporal thermalization process proceeds via a chain of intermediate Gibbs-like states. We specify the conditions under which this scenario occurs and corroborate the quantum equilibration with two different models.
