Fluctuations and control in the Vlasov-Poisson equation
Ricardo Lima, R. Vilela Mendes
In this paper we study the fluctuation spectrum of a linearized Vlasov-Poisson equation in the presence of a small external electric field. Conditions for the control of the linear…
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…
Non-permanent form solutions in the Hamiltonian formulation of surface water waves
Tounsia Benzekri, Ricardo Lima, Michel Vittot
Using the KAM method, we exhibit some solutions of a finite-dimensional approximation of the Zakharov Hamiltonian formulation of gravity water waves, which are spatially periodic,…
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…
On the convergence of multiplicative branching processes in dynamics of fluid flows
D. Volchenkov, R. Lima
The Brownian motion over the space of fluid velocity configurations driven by the hydrodynamical equations is considered. The Green function is computed in the form of an asymptoti…
