纳米线系统中的Majorana Josephson结在清洁极限下表现出伪4 π周期的电流-相位关系。在这项工作中，我们研究如何在Bogoliubov-de Gennes方法内的无序Majorana约瑟夫森结的电流相位关系响应于倾斜磁场。我们表明，倾斜磁场诱导的电流相位关系的一个phi（0）相移。最重要的是，我们发现，这种phi（0）-结的行为是强大的，即使在存在的障碍。(C)2017爱思唯尔B. V.保留所有权利。
Majorana Josephson junctions in nanowire systems exhibit a pseudo-4 pi period current-phase relation in the clean limit. In this work, we study how this current-phase relation responds to a tilted magnetic field in a disordered Majorana Josephson junction within the Bogoliubov-de Gennes approach. We show that the tilted magnetic field induces a phi(0) phase shift to the current-phase relation. Most importantly, we find that this phi(0)-junction behavior is robust even in the presence of disorders. (C) 2017 Elsevier B.V. All rights reserved.
