Orbital Design of Flat Bands in Non-Line-Graph Lattices via Line-Graph Wavefunctions
Hang Liu, Gurjyot Sethi, Sheng Meng +1
Line-graph (LG) lattices are known for having flat bands (FBs) from the destructive interference of Bloch wavefunctions encoded in pure lattice symmetry. Here, we develop a generic…

Flat-Bands-Enabled Triplet Excitonic Insulator in a Di-atomic Kagome Lattice
Gurjyot Sethi, Yinong Zhou, Linghan Zhu +2
The excitonic insulator (EI) state is a strongly correlated many-body ground state, arising from an instability in the band structure towards exciton formation. We show that the fl…
