Competition between ac driving-forces and Lévy flights in a nonthermal ratchet
Bao-quan Ai, Ya-feng He
Transport of overdamped particles in an asymmetrically periodic potential is investigated in the presence of Lévy noise and ac-driving forces. The group velocity is used to measure…
Transport in periodic potentials induced by fractional Gaussian noise
Bao-quan Ai, Ya-feng He, Wei-rong Zhong
Directed transport of overdamped Brownian particles driven by fractional Gaussian noises is investigated in asymmetrically periodic potentials. By using Langevin dynamics simulatio…
Transformation between dense and sparse spirals in symmetrical bistable media
Ya-feng He, Bao-quan Ai, Bambi Hu
Transformation between dense and sparse spirals is studied numerically based on a bistable FitzHugh-Nagumo model. It is found that the dense spiral can transform into two types of…
Time-delayed-feedback control of pattern formation in symmetrical bistable media
Ya-feng He, Bao-quan, Bambi Hu
Effects of time-delayed-feedback on pattern formation are studied in symmetrical bistable media. The results show that the time delay alters the behavior of the front bifurcation r…
Enhancement of the longitudinal transport by a weakly transversal drive
Yafeng He, Baoquan Ai
Transport of Brownian particles in a two-dimensional asymmetric tube is investigated by applying a polarized field. From the Brownian dynamics simulations we find that the longitud…
Directed transport driven by Lévy flights coexisting with subdiffusion
Bao-quan Ai, Ya-feng He
Transport of the Brownian particles driven by Lévy flights coexisting with subdiffusion in asymmetric periodic potentials is investigated in the absence of any external driving for…
