标题： Method for reliable realization of a varphi Josephson junction

摘要： 我们提出一种方法，通过将交替的0和$\pi$部分（子结）结合，实现一个$\phi$约瑟夫森结，其具有固有的非正弦电流-相位关系（CPR）。 分析了实现$\phi$基态的条件。 结果表明，考虑到“清洁结”中磁性（F）势垒的非正弦CPR，可以显著扩大$\phi$基态的区域（合适的F层厚度范围），并使$\phi$约瑟夫森结的实际实现成为可能。 这样的结点可能也有两个不同的稳定解，例如 0 和 $\pi$，0 和 $\phi$，或者 $\phi$ 和 $\pi$。 显示英文摘要

摘要： We propose a method to realize a $\phi$ Josephson junction by combining alternating 0 and $\pi$ parts (sub junctions) with an intrinsically non-sinusoidal current-phase relation (CPR). Conditions for the realization of the $\phi$ ground state are analyzed. It is shown that taking into account the non-sinusoidal CPR for a "clean junction with a ferromagnetic (F) barrier, one can significantly enlarge the domain (regime of suitable F-layer thicknesses) of the $\phi$ ground state and make the practical realization of $\phi$ Josephson junctions feasible. Such junctions may also have two different stable solutions, such as 0 and $\pi$, 0 and $\phi$, or $\phi$ and $\pi$.
