Abstract
We present results of numerical simulations for driven vortex lattices in the presence of a random disorder at zero temperature. We show that the plastic dynamics of vortices display dissipative chaos. Intermittency “routes to chaos” have clearly been identified below the differential resistance peak. The peak region is characterized by positive Lyapunov exponents, which are characteristic of chaos, and low frequency broad-band noise. Furthermore, we find a low fractal dimension of the strange attractor, which suggests that only a few dynamical variables are sufficient to model the complex plastic dynamics of vortices.
