摘要：

To reve al the non-Abelian braiding statistics of Major ana zero modes(MZMs),it is crucial to design a Majorana platform,in which MZMs can be easily manipulated in a broad topological nontrivial parameter space.This is also an essential step to confirm their existence.In this study,we propose an iron-based superconducting nanowire system with Majorana vortex states to satisfy desirable conditions.This system has a radius-induced topological phase transition,giving a lower bound for the nanowire radius.In the topological phase,the iron-based superconducting nanowires have only one pair of MZMs over a wide range of radii,chemical potential and external magnetic fields.The wave function of MZMs has a sizable distribution at the side edge of the nanowires.This property enables the control of the interaction of MZMs in neighboring vortex nanowires and paves the way for Majorana fusion and braiding.
