具有多个近邻化扇区的器件中的输运很大程度上取决于这些扇区配对能隙的复相位。我们研究了具有近邻化扇区和渐近正常引线的两终端和三终端设置中的磁性拓扑绝缘体纳米带。重点关注单手性马约拉纳费米子情况。手性马约拉纳费米子的特征电和热干涉可由配对的复相位控制。我们预测了交流马约拉纳效应，电压偏置引起的相位动力学产生可测量的随时间变化的电导振荡。当配置相对复相位时，具有超导岛的三终端结可用作马约拉纳路由器。
英文摘要
Transport in devices with multiple proximitized sectors depends heavily on the complex phases of the pairing gaps of those sectors. We investigate magnetic topological insulator nanoribbons in two- and three-terminal setups with proximitized sectors and asymptotic normal leads. Our focus is on the regime of single chiral Majoranas. The characteristic electric and thermal interferometries of chiral Majoranas can be controlled by the complex phases of the pairing. We predict an AC Majorana effect, in which phase dynamics induced by a voltage bias generate measurable time-dependent conductance oscillations. A three-terminal junction with superconducting islands can be used as a Majorana router when the relative complex phases are configured.
