Convective instability induced by nonlocality in nonlinear diffusive systems
Francesco Papoff, Roberta Zambrini
Abstract
We consider a large class of nonlinear diffusive systems with nonlocal coupling. By using a non-perturbative analytical approach we are able to determine the convective and absolute instabilities of all the uniform states of these systems. We find a huge window of convective instability that should provide a great opportunity to study experimentally and theoretically noise sustained patterns.
