Topological Crystalline Kondo Insulator in Mixed Valence Ytterbium Borides

Hongming Weng, Jianzhou Zhao, Zhijun Wang +2

The electronic structures of two mixed valence insulators YbB${}_6$ and YbB${}_{1}2$ are studied by using the local density approximation (LDA) supplemented with the Gutzwiller method an…
