Softening of a flat phonon mode in the kagome ScV6Sn6

Softening of a flat phonon mode in the kagome ScV6Sn6

Abstract Geometrically frustrated kagome lattices are raising as novel platforms to engineer correlated topological electron flat bands that are prominent to electronic instabilities. Here, we demonstrate a phonon softening at the k z  = π plane in ScV6Sn6. The low energy longitudinal phonon collaps...
