Taming Chaos in a Driven Josephson Junction

CONTROL OF CHAOS IN A DRIVEN NON LINEAR DYNAMICAL SYSTEM

We present a numerical study of a one-dimensional version of the Burridge-Knopoff model [16] of N-site chain of spring-blocks with stick-slip dynamics. Our numerical analysis and computer simulations lead to a set of different results corresponding to different boundary conditions. It is shown that we can convert a chaotic behaviour system to a highly ordered and periodic behaviour by making on...

Clustering Bifurcation and Spatiotemporal Intermittency in Rf-driven Josephson Junction Series Arrays

We study the spatiotemporal dynamics of the underdamped Josephson junction series arrays (JJSA) which are globally coupled through a resistive shunting load and driven by an rf bias current. Clustering bifurcations are shown to appear. In particular, cluster-doubling induced period-doubling bifurcations and clustering induced spatiotemporal chaos are found. Furthermore, an interesting spatiotem...

Bifurcation and chaos in a dc-driven long annular Josephson junction.

Experiments on intrinsic and thermally induced chaos in an rf-driven Josephson junction.

Anomalous transport in biased ac-driven Josephson junctions: Negative conductances

We investigate classical anomalous electrical transport in a driven, resistively, and capacitively shunted Josephson junction device. Intriguing transport phenomena are identified in chaotic regimes when the junction is subjected to both a time-periodic ac and a constant biasing dc current. The dependence of the voltage across the junction on the dc exhibits a rich diversity of anomalous transp...
