Weyl nodal line induced pairing in Ising superconductor and high critical field
Xiaoming Zhang, Feng Liu
Superconducting and topological states are two quantum phenomena attracting much interest. Their coexistence may lead to topological superconductivity sought-after for Majorana-bas…
Screening 2D materials with topological flat bands
Hang Liu, Sheng Meng, Feng Liu
Topological flat band (TFB) has been proposed theoretically in various lattice models, to exhibit a rich spectrum of intriguing physical behaviors. However, the experimental demons…
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…
