Chaotic hypothesis: Onsager reciprocity and fluctuation-dissipation theorem [PDF]

open access: yesJournal of Statistical Physics, 84, 899--926, 1996, 1995
It is shown that the "chaoticity hypothesis", analogous to Ruelle's principle for turbulence and recently introduced in statistical mechanics, implies the Onsager reciprocity and the fluctuation dissipation theorem in various models for coexisting transport phenomena.

Analytic Approach for Controlling Realistic Quantum Chaotic Systems

open access: yes, 2007

Multiple Chaotic Attractors in Coupled Lorenz Systems [PDF]

open access: yesarXiv, 2020
Unidirectionally coupled Lorenz systems in which the drive possesses a chaotic attractor and the response admits two stable equilibria in the absence of the driving is under investigation. It is found that double chaotic attractors coexist in the dynamics. The approach is applicable for chains of coupled Lorenz systems.

Sensitivity to perturbations in a quantum chaotic billiard

open access: yes, 2002
The Loschmidt echo (LE) measures the ability of a system to return to the initial state after a forward quantum evolution followed by a backward perturbed one.

The dynamical temperature and the standard map [PDF]

open access: yesPhysica A, v. 386, pp. 85-91 (2007), 2013
Numerical experiments with the standard map at high values of the stochasticity parameter reveal the existence of simple analytical relations connecting the volume and the dynamical temperature of the chaotic component of the phase space.

Decoherence of spin echoes

open access: yes, 2002
We define a quantity, the so-called purity fidelity, which measures the rate of dynamical irreversibility due to decoherence, observed e.g in echo experiments, in the presence of an arbitrary small perturbation of the total (system + environment ...

Variational method for locating invariant tori [PDF]

open access: yes, 2006
We formulate a variational fictitious-time flow which drives an initial guess torus to a torus invariant under given dynamics. The method is general and applies in principle to continuous time flows and discrete time maps in arbitrary dimension, and to ...

Hierarchy of random deterministic chaotic maps with an invariant measure [PDF]

open access: yes, 2003
Hierarchy of one and many-parameter families of random trigonometric chaotic maps and one-parameter random elliptic chaotic maps of $\bf{cn}$ type with an invariant measure have been introduced. Using the invariant measure (Sinai-Ruelle-Bowen measure), the Kolmogrov-Sinai entropy of the random chaotic maps have been calculated analytically, where the ...

Periodic orbit bifurcations and scattering time delay fluctuations

open access: yes, 2007
We study fluctuations of the Wigner time delay for open (scattering) systems which exhibit mixed dynamics in the classical limit. It is shown that in the semiclassical limit the time delay fluctuations have a distribution that differs markedly from those

Quantum Entanglement dependence on bifurcations and scars in non autonomous systems. The case of Quantum Kicked Top [PDF]

open access: yes, 2007
Properties related to entanglement in quantum systems, are known to be associated with distinct properties of the corresponding classical systems, as for example stability, integrability and chaos.
