Experiments Support Theory for Exotic Kagome States

O ne of the goals of condensed-matter physicists is to catalog and explain the wide array of electronic states that can appear in materials, improving researchers’ understanding of important phenomena such as superconductivity. In recent years, experimentalists have discovered several unexpected exotic electronic states in materials called kagome superconductors, prompting intense debate over the nature of these states. Now Ilija Zeljkovic of Boston College and his colleagues have discovered features in the band structures of these materials that point toward an explanation [1].
