Beyond kagome: $p$-bands in kagome metals

We review recent studies on quantum materials where transition-metal atoms give rise to $d$-bands typical of kagome metals. Using examples from several material families - AV${}_3$Sb${}_5$, FeGe, RV${}_6$Sn${}_6$, and LaRu${}_3$Si${}_2$ - we argue that $p$-bands contributed by elements beyond the kagome network also play a crucial role in the electronic instabilities, including the charge-density-waves and superconductivity in kagome metals.
