N ov 2 00 7 Non - Gaussian features of chaotic Hamiltonian transport
نویسنده
چکیده
Abstract. Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusion and the Burnett coefficients, which are obtained analytically. A characteristic time scale delimiting the onset of the Markovian regime for the master equation is established. Some explicit examples are discussed.

We present the complete calculation of the transverse momentum distribution for the decay b → sγ. The calculation of the coefficients of the infrared logarithms is performed using general properties of QCD. The resummation of large infrared logarithms is accomplished according to usual techniques of resummation. Non logarithmic terms (constants and function vanishing at the border of the phase ...

Modelling the chaotic states in terms of the Gaussian Orthogonal Ensemble of random matrices (GOE), we investigate the interaction of the GOE with regular bound states. The eigenvalues of the latter may or may not be embedded in the GOE spectrum. We derive a generalized form of the Pastur equation for the average Green’s function. We use that equation to study the average and the variance of th...

In this article, we present a numerical analysis concerning ray propagation in a multimode periodic segmented waveguide with a gaussian index segment profile. We show that this simple waveguide configuration exhibits a complex ray dynamics that can be regular or chaotic depending on the initial conditions.

As an important application of chaotic dynamical systems, chaos-based secure communication and cryptography attracted continuous interest over the last decade. It studies methods of controlling deterministic systems with chaotic behavior. Moreover, it is easy to notice the possibility of substantial variation of the characteristics of chaotic systems by relatively small variations of their para...
متن کاملN ov 1 99 3 Hamiltonian Maps and Transport in Structured Fluids
Structures such as waves, jets, and vortices have a dramatic impact on the transport properties of a flow. Passive tracer transport in incompressible two-dimensional flows is described by Hamiltonian dynamics, and, for idealized structures, the system is typically integrable. When such structures are perturbed, chaotic trajectories can result which can significantly change the transport propert...
