“…When the noise departs from Gaussian behavior, Li et al [60] researched the effects of superimposed roughness and noise parameters on the transport of particles in a triplewell potential under the action of Lévy noise. Wang et al [61] investigated the transport and diffusion of inertia Brownian particles in a periodic potential driven by non-Gaussian noise and found that for different values of noise intensity, the average velocity and the diffusion coefficient exhibit monotonic or non-monotonic dependence as correlation time increases. Consequently, as presently well researched, we can find little attention has been focused on the transport of the ABP induced by multiplicative and additive Gaussian colored noises in a new asymmetric bistable system with two biases.…”

The transport phenomena (drift and diffusion) of active Brownian particles in a new asymmetric bistable system with a linear bias force and a nonlinear bias force subjected to two colored noises are investigated. Two different biases break the symmetry of the potential to generate motion of the particle with a net velocity. Theoretical analysis of the system is given by virtue of the Langevin equation and the Fokker-Planck methods, which is verified by numerical simulation. The results show that: (i) coexistence of the linear bias and nonlinear bias is capable of tuning the transport of the particle, including current reversal, absolute negative mobility, directional transport; (ii) in the absence of linear bias F, the mean velocity is negative for positive nonlinear bias r but positive for negative r, that is, the nonlinear bias leads to absolute negative mobility. In the absence of nonlinear bias r, the mean velocity is positive for positive linear bias F and negative for negative F; (iii) as the absolute values of the linear bias and nonlinear bias increase, the mean velocity is promoted but the effective diffusion is suppressed; (iv) the enhancement of the multiplicative and additive noise intensities can suppress the transport and effective diffusion; and (v) the transport velocity and diffusion are facilitated with increasing the auto-correlation times of two colored noises. Furthermore, the physical mechanism for the particle’s transport is derived from the velocity distributions and the effective velocity potential gap of the above results.

“…[33][34][35][36][37][38][39][40] The non-Gaussian noise can be interpreted as more related to biological systems and natural phenomena. 37 Wang et al 36 investigated the transport phenomenon of inertia Brownian particles in the presence of the non-Gaussian noise and found that non-Gaussian noise can induce particles' directional movement (or diffusion), but Gaussian colored noise cannot. Wu et al 15 introduced non-Gaussian noise into stochastic resonance in a bistable system and concluded abundant phenomena of stochastic resonance.…”

The ratchet effect of an overdamped Brownian particle subjected to a spatially symmetric potential driven by a biharmonic temporal force is investigated when a non-Gaussian noise is considered. It is found that the noise intensity and the departure from the Gaussian noise will suppress the ratchet transport effect, while the noise color will strengthen the ratchet transport effect. In the same time, the phase difference mainly changes the direction of the transport. It is also shown that the abundant transport phenomenon is due to the breaking of symmetry for the biharmonic force.
