我们提出了简单的模型,典型的约瑟夫森棘轮的电流-电压特性。我们考虑的情况下,对一个恒定的施加反作用力的棘轮工作,并推导出这样的棘轮的关键特性的解析表达式:整流曲线,停止力,输入和输出功率,整流效率。棘轮性能的优化进行了讨论。
We propose simple models for the current-voltage characteristics of typical Josephson ratchets. We consider the case of a ratchet working against a constant applied counter force and derive analytical expressions for the key characteristics of such a ratchet: rectification curve, stopping force, input and output powers, and rectification efficiency. Optimization of the ratchet performance is discussed.
