Pseudospin-selective Floquet band engineering in black phosphorus
Shaohua Zhou, Changhua Bao, Benshu Fan +10
Time-periodic light field has emerged as a control knob for manipulating quantum states in solid-state materials, cold atoms and photonic systems via hybridization with photon-dres…
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…
Screening magnetic two-dimensional atomic crystals with nontrivial electronic topology
Hang Liu, Jia-Tao Sun, Miao Liu +1
To date only a few two-dimensional (2D) magnetic crystals were experimentally confirmed, such as CrI3 and CrGeTe3, all with very low Curie temperatures (TC). High-throughput first-…
Photoinduced topological phase transitions in strained black phosphorus
Hang Liu, Jia-Tao Sun, Cai Cheng +2
Photoinduced topological phase transitions (TPTs) in black phosphorous (BP) under compressive strain were investigated by combining Floquet theory and first-principles calculations…
