热力学平衡附近涨落的速度
On the speed of fluctuations around thermodynamic equilibrium
摘要：
我们研究了量子系统在热力学平衡态附近的涨落速度，证明了在典型的热力学情形下，涨落速度几乎在所有时间都是极小的。这里考虑的设置是量子系统耦合到浴，两者共同描述为一个封闭系统。这一点，与《易经》中所讲的一样。Linden等人，物理评论E 79：061103（2009）]和"热力学平衡态“指的是包括通常的热力学平衡情况以及更一般的情况的情况。
英文摘要：
We study the speed of fluctuation of a quantum system around its thermodynamic equilibrium state, and show that the speed will be extremely small for almost all times in typical thermodynamic cases. The setting considered here is that of a quantum system couples to a bath, both jointly described as a closed system. This setting, is the same as the one considered in [N. Linden et al., Phys. Rev. E 79:061103 (2009)] and the ``thermodynamic equilibrium state'' refers to a situation that includes the usual thermodynamic equilibrium case, as well as far more general situations.
