Diffusive transport and self-consistent dynamics in coupled maps
Guido Boffetta, Diego del-Castillo-Negrete, Cristobal Lopez +2
The study of diffusion in Hamiltonian systems has been a problem of interest for a number of years. In this paper we explore the influence of self-consistency on the diffusion prop…
Sand stirred by chaotic advection
Cristobal Lopez, Andrea Puglisi
We study the spatial structure of a granular material, N particles subject to inelastic mutual collisions, when it is stirred by a bidimensional smooth chaotic flow. A simple dynam…
Excitable media in open and closed chaotic flows
Zoltan Neufeld, Cristobal Lopez, Emilio Hernandez-Garcia +1
We investigate the response of an excitable medium to a localized perturbation in the presence of a two-dimensional smooth chaotic flow. Two distinct types of flows are numerically…
Spatial Patterns in Chemically and Biologically Reacting Flows
Emilio Hernandez-Garcia, Cristobal Lopez, Zoltan Neufeld
We present here a number of processes, inspired by concepts in Nonlinear Dynamics such as chaotic advection and excitability, that can be useful to understand generic behaviors in…
Efficiency of a stirred chemical reaction in a closed vessel
Cristobal lopez, Davide Vergni, Angelo Vulpiani
We perform a numerical study of the reaction efficiency in a closed vessel. Starting with a little spot of product, we compute the time needed to complete the reaction in the conta…
