Tunable Majorana corner states in a two-dimensional second-order topological superconductor induced by magnetic fields

27 May 2018 Zhu Xiaoyu

A two-dimensional second-order topological superconductor exhibits a finite gap in both bulk and edges, with the nontrivial topology manifesting itself through Majorana zero modes localized at the corners, i.e., Majorana corner states. We investigate a time-reversal-invariant topological superconductor in two dimension and demonstrate that an in-plane magnetic field could transform it into a second-order topological superconductor...
