However, in CsCr₃Sb₅, researchers have found that the flat bands are actively involved, directly affecting the material’s superconducting and magnetic properties, making it a rare platform for studying quantum phenomena.

New pathway to engineer exotic superconductivity

A recent study, led by Pengcheng Dai, Ming Yi, and Qimiao Si of Rice University’s Department of Physics and Astronomy and Smalley-Curl Institute, along with Di-Jing Huang from Taiwan’s National Synchrotron Radiation Research Center, has been focusing on the chromium-based kagome metal CsCr₃Sb₅.

Published in Nature Communications, the research examines how this material, which exhibits superconductivity under pressure, hosts active flat electronic bands that directly influence its quantum properties, offering new insights into the design of unconventional superconductors and other advanced quantum materials.
