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…

Orbital design of topological insulators from two-dimensional semiconductors
Lei Gao, Jia-Tao Sun, Gurjyot Sethi +3
Two-dimensional (2D) materials have attracted much recent attention because they exhibit various distinct intrinsic properties/functionalities, which are, however, usually not inte…
