Compounds with kagome lattice usually host many exotic quantum states, including the quantum spin liquid, non-trivial topological Dirac bands and a strongly renormalized flat band, etc. Recently an interesting vanadium based kagome family $A{\mathrm{V}}_{3}{\mathrm{Sb}}_{5}$ $(A=\mathrm{K},\mathrm{Rb},\text{or}\phantom{\rule{0.28em}{0ex}}\mathrm{Cs})$ was discovered, and these materials exhibit multiple interesting properties, including unconventional saddle-point driving charge density …
