Fluctuation Relations and Nonequilibrium Response for Chaotic Dissipative Dynamics

- Physics
- 2013

In a recent paper [Colangeli and Rondoni, Physica D 241:681, 2011] it was argued that the Fluctuation Relation for the phase space contraction rate Λ could suitably be extended to non-reversible…

Beyond the linear fluctuation-dissipation theorem: the role of causality

- Physics
- 2012

In this paper we tackle the traditional problem of relating the fluctuations of a system to its response to external forcings and extend the classical theory in order to be able to encompass also…

Handy fluctuation-dissipation relation to approach generic noisy systems and chaotic dynamics.

- PhysicsPhysical review. E

A general formulation of the fluctuation-dissipation relations (FDRs) holding also in far-from-equilibrium stochastic dynamics, and allows to reproduce, in a suitable small-noise limit, the response functions of deterministic, strongly nonlinear dynamical models, even in the presence of chaotic behavior.

Resonances in a Chaotic Attractor Crisis of the Lorenz Flow

Local bifurcations of stationary points and limit cycles have successfully been characterized in terms of the critical exponents of these solutions. Lyapunov exponents and their associated covariant…

Physical Ergodicity and Exact Response Relations for Low-dimensional Maps

Recently, novel ergodic notions have been introduced in order to find physically relevant formulations and derivations of fluctuation relations. These notions have been subsequently used in the…

Crisis of the chaotic attractor of a climate model: a transfer operator approach

- Physics

The destruction of a chaotic attractor leading to rough changes in the dynamics of a dynamical system is studied. Local bifurcations are known to be characterised by a single or a pair of…

On Some Aspects of the Response to Stochastic and Deterministic Forcings

The perturbation theory of operator semigroups is used to derive response formulas for a variety of combinations of acting forcings and reference background dynamics. We decompose the response…

Revising and Extending the Linear Response Theory for Statistical Mechanical Systems: Evaluating Observables as Predictors and Predictands

- MathematicsJournal of Statistical Physics
- 2018

The rigid separation between forcing and response is broken, which is key in linear response theory, and the concept of causality is revisited, finding that not all observables are equally good as predictors when a given forcing is applied.

Towards a General Theory of Extremes for Observables of Chaotic Dynamical Systems

- Mathematics, PhysicsJournal of statistical physics
- 2014

It is derived that the shape parameter does not depend on the chosen observables, but only on the partial dimensions of the invariant measure on the stable, unstable, and neutral manifolds.

It has been rigorously shown in [11] that the complex susceptibility for chaotic maps of the interval can have a pole in the upper complex plane. I develop a numerical procedure allowing to exhibit…

This paper reviews various applications of the theory of smooth dynamical systems to conceptual problems of nonequilibrium statistical mecanics. We adopt a new point of view which has emerged…

Stable resonances and signal propagation in a chaotic network of coupled units.

This dynamic differentiation, induced by nonlinearities, exhibits the different ability that units have to transmit a signal in this network of nonlinearly interacting units.

Transmitting a signal by amplitude modulation in a chaotic network

How the dynamics may interfere with the graph topology to produce an effective transmission network, whose topology depends on the signal, and cannot be directly read on the "wired" network is discussed.

Field driven thermostated systems: A nonlinear multibaker map

In this paper we discuss a simple deterministic model for a field driven, thermostated random walk that is constructed by a suitable generalization of a multibaker map. The map is a usual multibaker,…

Linear response of the Lorenz system.

The present results indicate that in contrast to a recent speculation the large system limit (thermodynamic limit) need not be invoked to obtain a linear response for chaotic systems of this type.
