    Imaging real-space flat band localization in kagome magnet FeSn

    Kagome lattices host flat bands due to their frustrated lattice geometry, which leads to destructive quantum interference of electron wave functions. Here, we report imaging of the kagome flat band localizatio...

    Evidence of a room-temperature quantum spin Hall edge state in a higher-order topological insulator

    Room-temperature realization of macroscopic quantum phases is one of the major pursuits in fundamental physics1,2. The quantum spin Hall phase3–6 is a topological quantum phase that features a two-dimensional ins...

    Unconventional chiral charge order in kagome superconductor KV3Sb5

    Intertwining quantum order and non-trivial topology is at the frontier of condensed matter physics1–4. A charge-density-wave-like order with orbital currents has been proposed for achieving the quantum anomalous ...
