Abstract

We consider the problems related to the use of 0–π junctions with a nontrivial current–phase relation in Josephson transmission lines. The various types of excitations (fractional fluxons) propagating in such Josephson media have been studied. We have investigated the problem of the integration of Josephson transmission lines consisting of 0–π junctions (nontrivial Josephson transmission lines) with ordinary rapid single-flux-quantum electronics. We have analyzed the characteristic excitation transformation processes at the interfaces of ordinary and nontrivial Josephson transmission lines, which are largely similar to the Andreev reflections from a superconductor–normal metal interface.

Josephson 介质中分数通量子的生成和传播

摘要

我们考虑与在约瑟夫森传输线中使用具有非平凡电流-相位关系的 0-π 结相关的问题。已经研究了在这种约瑟夫森介质中传播的各种类型的激发（分数通量子）。我们研究了由 0-π 结（非平凡约瑟夫森传输线）组成的约瑟夫森传输线与普通快速单通量量子电子器件的集成问题。我们已经分析了普通和非平凡约瑟夫森传输线界面处的特征激发转换过程，这些过程与来自超导体-普通金属界面的 Andreev 反射非常相似。
