Abstract:
Kagome materials exhibit a variety of rich physical properties due to the emergence of diverse electronic phases. AV3Sb5 has garnered substantial interest for its coexisting charge orders, superconductivity, and controversial time-reversal symmetry breaking. More recently, the bilayer kagome ScV6Sn6 has also drawn attention as it exhibits a charge density wave (CDW) with a distinct wave vector without superconductivity. This raises the question: What is occurring in bilayer kagome ScV6Sn6? Our work aims to unravel the mysteries of bilayer kagome ScV6Sn6 and beyond, highlighting the rich physical properties induced by flat bands, potential CDW transitions, as well as their interplay with magnetism.
