Credit: Zijia Cheng Adding impurities is a useful way to learn about the behavior of superconductors, said M. Zahid Hasan, the Eugene Higgins Professor of Physics at Princeton University, who led the research team. Indeed, despite the relatively large number of confirmed Weyl and Dirac systems , few show band crossings in close proximity to the Fermi level. While such states have been reported in high-temperature superconductors and dilute magnetic semiconductors, they are unexplored in topological magnets which can feature spin-orbit tunability.

Zijia’s education is listed on their profile. A longstanding idea known as Anderson’s theorem predicts that although adding impurities can introduce disorder into a superconductor, in many cases, it will not destroy the superconductivity. Owing to the unusual lattice geometry and breaking of time-reversal symmetry, kagome magnets are predicted to support intrinsic Chern quantum phases.
