Flat bands, non-trivial band topology and electronic nematicity in layered kagome-lattice RbTi${}_3$Bi${}_5$

Zhicheng Jiang, Zhengtai Liu, Haiyang Ma +15

Layered kagome-lattice materials with 3$d$ transition metals provide a fertile playground for studies on geometry frustration, band topology and other novel ordered states. A repre…
