非平衡态的涨落与响应

Fluctuations and response of nonequilibrium states

Marco Baiesi, Christian Maes, Bram Wynants

摘要:

一个广义的波动响应关系被发现驱动的热系统的平衡。它的推导与动力学的许多细节无关,只需要是一阶的。结果给出了一个修正的平衡涨落耗散定理,在可观察的和过剩的动力学活动的扰动所造成的。以前的方法来解决这个问题的恢复和扩展在一个统一的计划。

英文摘要:

A generalized fluctuation-response relation is found for thermal systems driven out of equilibrium. Its derivation is independent of many details of the dynamics, which is only required to be first-order. The result gives a correction to the equilibrium fluctuation-dissipation theorem, in terms of the correlation between observable and excess in dynamical activity caused by the perturbation. Previous approaches to this problem are recovered and extended in a unifying scheme.
