A new Majorana platform in an Fe-As bilayer superconductor

A new Majorana platform in an Fe-As bilayer superconductor

Iron-pnictide superconductors share similar topological band structure with iron-chalcogenide superconductors, but no Majorana modes have been observed in the former. Here, the authors observe both the superconducting Dirac surface states and Majorana zero modes inside its vortex cores in CaKFe4As4.
