涨落定理、非线性响应和时间反演对称性的规律性

Fluctuation Theorem, non linear response and the regularity of time reversal symmetry

Marcello Porta

摘要:

Gallavotti-Cohen涨落定理(FT)暗示了关联函数之间的无穷多个恒等式,这些恒等式可以看作是格林久保公式在非线性区域的推广。作为应用,我们讨论了一个微扰检查FT关系通过这些身份为一个简单的Anosov可逆系统,我们发现,缺乏可微的时间反演对称性意味着违反的Gallavotti -科恩波动关系。最后,与Lebowitz - Spohn FT作了简要比较.

英文摘要:

The Gallavotti - Cohen Fluctuation Theorem (FT) implies an infinite set of identities between correlation functions that can be seen as a generalization of Green Kubo formula to the nonlinear regime. As an application, we discuss a perturbative check of the FT relation through these identities for a simple Anosov reversible system; we find that the lack of differentiability of the time reversal symmetry implies a violation of the Gallavotti - Cohen fluctuation relation. Finally, a brief comparison with Lebowitz - Spohn FT is reported.
