Spin excitations and flat electronic bands in a Cr-based kagome superconductor

Abstract In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs) from the quantum destructive interference of the electronic wavefunction. Tuning an FB to the chemical potentia...
