چکیده انگلیسی
In this paper, we investigate the role of correlated multiplicative (κ1) and additive (κ2) noises in a modified energy conversion depot model, at which it is added a linear term in the conversion of internal energy of active Brownian particles (ABPs). The linear term (a1â 0.0) in energy conversion model breaks the symmetry of the potential to generate motion of the ABPs with a net transport velocity. Adopt a nonlinear Langevin approach, the transport properties of the ABPs have been discussed, and our results show that: (i) the transport velocity ãÏ
1ã of the ABPs are always positive whether the correlation intensity λ=0.0 or not; (ii) for a small value of the multiplicative noise intensity κ1, the variation of ãÏ
1ã with λ shows a minimum, there exists an optimal value of the correlation intensity λ at which the ãÏ
1ã of the ABPs is minimized. But for a large value of κ1, the ãÏ
1ã monotonically decreases; (iii) the transport velocity ãÏ
1ã increases with the increase of the κ1 or κ2, i.e., the multiplicative or additive noise can facilitate the transport of the ABPs; and (iv) the effective diffusion increases with the increase of a1, namely, the linear term in modified energy conversion model of the ABPs can enhance the diffusion of the ABPs.
