论文摘要
我们考虑在横向磁场中拓扑绝缘子顶部的约瑟夫森连接处的Majorana零模式。 Majorana零模式位于约瑟夫森涡流的定期定位节点。我们发现，这些模式的杂交被问题的对称性在消失的化学潜力时所禁止，从而确保更好地保护零模式，并产生方法来控制Majorana模式之间用于量子信息处理应用程序之间的隧道耦合。
We consider Majorana zero modes in a Josephson junction on top of a topological insulator in transverse magnetic field. Majorana zero modes reside at periodically located nodes of Josephson vortices. We find that hybridization of these modes is prohibited by symmetries of the problem at vanishing chemical potential, which ensures better protection of zero modes and yields methods to control the tunnel coupling between Majorana modes for quantum information processing applications.
