Majorana Fermions in Periodically Driven Semiconductor-Superconductor Heterostructure
Abstract
We propose a new approach to create Majorana fermions at the edge of a periodically driven semiconductor-superconductor Heterostructure. We calculate the quasi-energy spectrum of the periodically driven Heterostructure by using the Floquet's theory. When the interaction between different Brillouin zones of quasi-energy is neglected, one Majorana fermion can be created at each edge of the Heterostructure when the ratio of driven amplitude and driven frequency is larger than a minimum. Furthermore, when the interaction between the nearest Brillouin zones of quasi-energy is considered, we restrict the condition of creating Majorana fermions above with a lower limit of the driven frequency. We also discuss the experimental protocol of creating Majorana fermions in the periodically driven Heterostructure.
