Intermittency Route to Strange Nonchaotic Attractors
نویسندگان
چکیده
Strange nonchaotic attractors (SNA) arise in quasiperiodically driven systems in the neighborhood of a saddle node bifurcation whereby a strange attractor is replaced by a periodic (torus) attractor. This transition is accompanied by Type-I intermittency. The largest nontrivial Lyapunov exponent Λ is a good order–parameter for this route from chaos to SNA to periodic motion: the signature is distinctive and unlike that for other routes to SNA. In particular, Λ changes sharply at the SNA to torus transition, as does the distribution of finite–time or N–step Lyapunov exponents, P(ΛN ). Typeset using REVTEX

Blowout Bifurcation Route to Strange Nonchaotic Attractors.
Strange nonchaotic attractors are attractors that are geometrically strange, but have nonpositive Lyapunov exponents. We show that for dynamical systems with an invariant subspace in which there is a quasiperiodic torus, the loss of the transverse stability of the torus can lead to the birth of a strange nonchaotic attractor. A physical phenomenon accompanying this route to strange nonchaotic a...
متن کاملStrange Nonchaotic Attractors in the Quasiperiodically forced Logistic Map
Different mechanisms for the creation of strange non-chaotic dynamics in the quasiperiodically forced logistic map are studied. These routes to strange nonchaos are characterised through the behavior of the largest nontrivial Lyapunov exponent, as well as through the characteristic distributions of finite time Lyapunov exponents. Strange nonchaotic attractors can be created at a saddle–node bif...
متن کاملMechanism for the intermittent route to strange nonchaotic attractors.
Intermittent strange nonchaotic attractors (SNAs) appear typically in quasiperiodically forced period-doubling systems. As a representative model, we consider the quasiperiodically forced logistic map and investigate the mechanism for the intermittent route to SNAs using rational approximations to the quasiperiodic forcing. It is found that a smooth torus transforms into an intermittent SNA via...
متن کاملStrange Nonchaotic attractors from periodically excited Chua's Circuit
Strange nonchaotic attractor refers to an attractor which is geometrically strange (fractal) but nonchaotic (i.e. typical orbits have nonpositive Lyapunov exponents). Since the pioneering work of Grebogi et al. [1984], much research has been carried out to show the existence, characterization and mechanisms for the creation of attractors in quasiperiodically excited systems [Romeiras & Ott, 198...
متن کاملFractal properties of robust strange nonchaotic attractors in maps of two or more dimensions.
We consider the existence of robust strange nonchaotic attractors in a simple class of quasiperiodically forced systems. Rigorous results are presented demonstrating that the resulting attractors are strange in the sense that their box-counting dimension D0 is larger than their information dimension D1 by 1 (i.e., D(0)=D(1)+1). We also show how this property is manifested in numerical experiments.
