The material search for topological superconductors is fueled by the prediction of Majorana zero modes (MZM), which are exotic boundary excitations that are candidates for topological qubits. Yet, materials hosting topological superconductivity with MZMs are still rare to date. In this talk, I will theoretically show that monolayer WTe2 and three-dimensional MoTe2 could host MZMs at corners. Then, I will present comprehensive recipes for finding such ‘higher-order’ topological superconductors. Finally, by combining mathematically derived topological invariants and high-throughput DFT band structure calculations, I will discuss a large-scale systematic search for topological superconductors over material databases.
