Topological superconductors possess Majorana modes at the edge and are important in future quantum computational devices. The authors theoretically demonstrate the Larkin-Ovchinnikov superconducting phase can be topologically non-trivial in certain sandwich structure or iron-based superconductor films and possess a chain of Majorana modes.
