Control of chaotic advection
Tounsia Benzekri, Cristel Chandre, Xavier Leoncini +4
A method of chaos reduction for Hamiltonian systems is applied to control chaotic advection. By adding a small and simple term to the stream function of the system, the constructio…
Stabilizing the intensity of a wave amplified by a beam of particles
Romain Bachelard, Andrea Antoniazzi, Cristel Chandre +3
The intensity of an electromagnetic wave interacting self-consistently with a beam of charged particles as in a free electron laser, displays large oscillations due to an aggregate…
Phase space structures and ionization dynamics of hydrogen atom in elliptically polarized microwaves
Elena Shchekinova, Cristel Chandre, Turgay Uzer
The multiphoton ionization of hydrogen atoms in a strong elliptically polarized microwave field exhibits complex features that are not observed for ionization in circular and linea…
Channeling chaotic transport in a wave-particle experiment
Alessandro Macor, Fabrice Doveil, Cristel Chandre +3
A numerical and experimental study of a control method aimed at channeling chaos by building barriers in phase space is performed on a paradigm for wave-particle interaction, i.e.,…
Control of the chaotic velocity dispersion of a cold electron beam interacting with electrostatic waves
Guido Ciraolo, Cristel Chandre, Ricardo Lima +2
In this article we present an application of a method of control of Hamiltonian systems to the chaotic velocity diffusion of a cold electron beam interacting with electrostatic wav…
From chaos of lines to Lagrangian structures in flux conservative fields
Xavier Leoncini, Olivier Agullo, Magali Muraglia +1
A numerical method is proposed in order to track field lines of three-dimensional divergence free fields. Field lines are computed by a locally valid Hamiltonian mapping, which is…
