摘要
研究了确定性周期闪烁棘齿势下欠阻尼的二维硬球系统的合作定向输运问题.结果表明,硬球之间的碰撞有利于定向输运,输运速度与硬球半径有关,因而该模型可用于粒子分离.
The cooperative transport in a two-dimensional system of hard halls is studied, which is underdamped and under the deterministically flashing ratchet potential. It is found that the collision can favor the transport and the velocity relates to the radius. Thus, this model can be used to separate particles.
