Facilitated movement of inertial Brownian motors driven by a load under an asymmetric potential
Bao-quan Ai, Liang-gang Liu
Based on recent work [L. Machura, M. Kostur, P. Talkner, J. Luczka, and P. Hanggi, Phys. Rev. Lett. 98, 040601 (2007)], we extend the study of inertial Brownian motors to the case…
