چکیده

The relation between a recently introduced dynamical real space renormalization group and the fluctuation-dissipation theorem is discussed. An apparent incompatibility is pointed out and resolved. PACS numbers:61.50.Cj,05.40.+j,05.70.Ln,64.60.Ak

New Approximations and Tests of Linear Fluctuation-Response for Chaotic Nonlinear Forced-Dissipative Dynamical Systems

We develop and test two novel computational approaches for predicting the mean linear response of a chaotic dynamical system to small change in external forcing via the fluctuation-dissipation theorem. Unlike the earlier work in developing fluctuationdissipation theorem-type computational strategies for chaotic nonlinear systems with forcing and dissipation, the new methods are based on the the...

Fluctuation relations for diffusion that is thermally driven by a nonstationary bath.

In the context of the Markovian dynamical evolution in a nonstationary thermal bath, we construct a family of fluctuation relations for the entropy production that are not verified by the work performed on the system. We exhibit fluctuation relations, which are global versions either of the generalized fluctuation-dissipation theorem around a nonequilibrium diffusion or of the usual fluctuation...

On the Perturbation Expansion of the KPZ- Equation

Thanks to a fluctuation dissipation theorem and the mapping to exactly solvable models, much is known for space-dimension d = 1 [1, 2, 3]. In contrast, the case of d ≥ 2 can only be attacked by approximative methods or field-theoretic perturbative expansions. Using the latter, the fixed point structure of the renormalization group flow for d = 2 + ε has been obtained [1, 4, 5]. Two domains can ...

Blended Response Algorithms for Linear Fluctuation-Dissipation for Complex Nonlinear Dynamical Systems

In a recent paper the authors developed and tested two novel computational algorithms for predicting the mean linear response of a chaotic dynamical system to small changes in external forcing via the fluctuation-dissipation theorem (FDT): the short-time FDT (ST-FDT), and the hybrid Axiom A FDT (hA-FDT). Unlike the earlier work in developing fluctuation-dissipation theorem-type computational st...
