Multiple topological states in iron-based superconductors (original) (raw)

AI-generated Abstract

This research investigates the coexistence of topological states and superconductivity in iron-based superconductors, revealing that various compounds—including Li(Fe,Co)As and Fe(Te,Se)—exhibit non-trivial topological band structures near the Fermi level. The findings, supported by advanced laser-based spin-resolved and angle-resolved photoemission spectroscopy (ARPES), suggest that the integration of topological states with superconductivity could lead to novel superconducting phenomena, including surface and bulk topological superconductivity.
