- 論文の詳細を見る
A Langevin equation is proposed to perforzn a sinaulation for the Feynman ratchet model.A stochastic boundary condition is introdvxced for tlae role of a pawl in tl'xe Feynman ratchetmodel. The rtaatl'xetnatical naodel can be solved trsing the Fokker-Planck eqtration, The solutionis compared with the Langevin simulation. A coupled system of the ratchet elements exhibitssmooth unidirectional raaotion when the cotzpling constant is large.
