The real butterfly effect: from the pop culture to mathematics and physics
Victor de Jesus Valadão, Erik Aurell, Guido Boffetta +3
The "butterfly effect", introduced over half a century ago by Edward Lorenz, has shifted from a cornerstone of dynamical systems to a popular metaphor, yet its true physical manife…
Relaxation of finite perturbations: Beyond the Fluctuation-Response relation
G. Boffetta, G. Lacorata, S. Musacchio +1
We study the response of dynamical systems to finite amplitude perturbation. A generalized Fluctuation-Response relation is derived, which links the average relaxation toward equil…
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…
Front speed enhancement in cellular flows
M. Abel, M. Cencini, D. Vergni +1
The problem of front propagation in a stirred medium is addressed in the case of cellular flows in three different regimes: slow reaction, fast reaction and geometrical optics limi…
