Resonant current in coupled inertial Brownian particles with delayed-feedback control
Tianfu Gao, Zhigang Zheng, Jincan Chen
The transport of a walker in rocking feedback-controlled ratchets are investigated. The walker consists of two coupled "feet" that allow the interchange of the order of the particl…
Array-induced collective transport in the Brownian motion of coupled nonlinear oscillator systems
Zhigang Zheng, Bambi Hu, Gang Hu
Brownian motion of an array of harmonically coupled particles subject to a periodic substrate potential and driven by an external bias is investigated. In the linear response limit…
Resonant steps and spatiotemporal dynamics in the damped dc-driven Frenkel-Kontorova chain
Zhigang Zheng, Bambi Hu, Gang Hu
Kink dynamics of the damped Frenkel-Kontorova (discrete sine-Gordon) chain driven by a constant external force are investigated. Resonant steplike transitions of the average veloci…
Spatiotemporal dynamics of discrete sine-Gordon lattices with sinusoidal couplings
Zhigang Zheng, Bambi Hu, Gang Hu
The spatiotemporal dynamics of a damped sine-Gordon chain with sinusoidal nearest-neighbor couplings driven by a constant uniform force are discussed. The velocity characteristics…
