    Solitons, spatiotemporal chaos and synchronization in arrays of damped driven nonlinear oscillators
    (2008) Robinson, William Michael Lewin; Barashenkov, Igor; Alexeeva, Nora
    Simulating the homogeneous chain, we demonstrate the existance of periodically oscillating solitons, the period-doubling sequence of transitions to temporal chaos and the degeneration into spatiotemporal chaos for larger driving strengths. Next, we explore the effect of introducing weak disorder in the simplest form, a single impurity, into the chain. We describe how a long impurity can induce a pinned soliton to form and prevent spatiotemporal chaos, synchronizing the oscillators in the chain. Lastly we study chains with several impurities in various configurations.
