标题： Inverse ac Josephson effect in Josephson diode

摘要： 我们研究了约瑟夫森结，在该结中非互易临界电流是由连接的$4\pi$周期和$2\pi$周期电流-相位关系相互作用诱导的。 我们采用了作为具有非互易临界电流的约瑟夫森二极管的拓扑结模型。 对于这种约瑟夫森二极管，我们演示了一种逆向交流约瑟夫森效应，其中纯交流驱动电流感应出有效的直流电压。 我们表明这种逆向交流约瑟夫森效应源于系统非互易临界电流的电压整流。 我们探讨了感应直流电压对交流驱动电流的幅度和频率的依赖性，并揭示了逆向交流约瑟夫森效应的最佳条件。 显示英文摘要

摘要： We study the Josephson junction where nonreciprocal critical current was induced by the interplay of the $4\pi$-periodic and $2\pi$-periodic current-phase relation of the junction. We take the model of a topological junction which serves as a Josephson diode with nonreciprocal critical currents. For this Josephson diode, we demonstrate an inverse ac Josephson effect where an effective dc voltage is induced by a pure ac driving current. We show that this inverse ac Josephson effect originates from the voltage rectification by the nonreciprocal critical current of the system. We explore the dependence of the induced dc voltage on the amplitude and frequency of the ac driving current and reveal the optimized condition for the inverse ac Josephson effect.
