Gallavotti和Cohen的涨落定理适用于经历Langevin动力学的有限系统。在这样的背景下，所有非平凡的遍历理论问题都被绕过了，并且定理采用了特别简单的形式。作为特例，我们得到了一个适用于任意强场扰动平衡系统的非线性涨落耗散定理。
The fluctuation theorem of Gallavotti and Cohen holds for finite systems undergoing Langevin dynamics. In such a context all non-trivial ergodic theory issues are bypassed, and the theorem takes a particularly simple form. As a particular case, we obtain a nonlinear fluctuation-dissipation theorem valid for equilibrium systems perturbed by arbitrarily strong fields.
