Higher-order topological superconductivity in monolayer Fe(Te,Se)

Majorana zero modes have attracted tremendous attention due to their critical role in topological quantum computation. Current major experimental efforts focus on the hetero-structure approach, which is challenging due to the complexity of the interface. Recently, the discovery of topological properties in high-Tc iron-based superconductors provides an ideal Majorana platform. An international team from USA, Germany and China proposes to realize Majorana zero modes in monolayer Fe(Te,Se) by applying an in-plane magnetic field and electric gating.
