两个耦合约瑟夫森结中输运特性的控制

Control of transport characteristics in two coupled Josephson junctions

J. Spiechowicz, L. Machura, M. Kostur, J. Luczka

摘要:

我们报告的两个耦合约瑟夫森结的输运性质的理论研究和比较两种情况下控制的电流-电压特性时,系统是由一个外部偏置的直流电流和无偏置的交流电流组成的一个谐波。在第一种情况下,只有一个结受到直流和交流电流。在第二种情况下,信号被分离--一个结点经受直流电流,而另一个结点经受交流电流。我们研究了两个路口的直流电压,并发现第一和第二驱动方案的异常运输制度的多样性。

英文摘要:

We report on a theoretical study of transport properties of two coupled Josephson junctions and compare two scenarios for controlling the current-voltage characteristics when the system is driven by an external biased DC current and unbiased AC current consisting of one harmonic. In the first scenario, only one junction is subjected to both DC and AC currents. In the second scenario the signal is split -- one junction is subjected to the DC current while the other is subjected to the AC current. We study DC voltages across both junctions and find diversity of anomalous transport regimes for the first and second driving scenarios.
