摘要

We review recent progress in the exploration of topological quantum states of matter in iron-based superconductors.In particular,we focus on the non-trivial topology existing in the band structures and superconducting states of iron's 3d orbitals.The basic concepts,models,materials and experimental results are reviewed.The natural integration between topology and high-temperature superconductivity in iron-based superconductors provides great opportunities to study topological superconductivity and Majorana modes at high temperature.
