Crisis-induced intermittency due to attractor-widening in a buoyancy-driven solar dynamo
Eurico Covas, Mathieu Ossendrijver
In a recent paper [M. A. J. H. Ossendrijver, A&A {\bf 359}, 364 (2000)] numerical simulations of a 2D mean--field model where shown to produce grand minima, typical of the long-ter…
The influence of noise on scalings for in-out intermittency
Peter Ashwin, Eurico Covas, Reza Tavakol
We study the effects of noise on a recently discovered form of intermittency, referred to as in-out intermittency. This type of intermittency, which reduces to on-off in systems wi…
In--out intermittency in PDE and ODE models
Eurico Covas, Reza Tavakol, Peter Ashwin +2
We find concrete evidence for a recently discovered form of intermittency, referred to as in--out intermittency, in both PDE and ODE models of mean field dynamos. This type of inte…
Absence of supersensitivity to small input signals in generalized on--off systems
Eurico Covas, Reza Tavakol
It has recently been shown that nonlinear skew product dynamical systems with invariant subspaces which are capable of displaying on-off intermittency can show supersensitivity to…
