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…
Negative Interatomic Spring Constant Manifested by Topological Phonon Flat Band
Bowen Xia, Hang Liu, Feng Liu
Phonons as bosons are different from electrons as fermions. Unlike interatomic electron hopping that can be either positive or negative and further tuned by spin-orbit coupling, in…
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…
Excited quantum Hall effect: enantiomorphic flat bands in a Yin-Yang Kagome lattice
Yinong Zhou, Gurjyot Sethi, Hang Liu +2
Quantum Hall effect (QHE) is one of the most fruitful research topics in condensed-matter physics. Ordinarily, the QHE manifests in a ground state with time-reversal symmetry broke…
Superstructure-induced splitting of Dirac cones in silicene
B. Feng, H. Zhou, Y. Feng +8
Atomic scale engineering of two-dimensional materials could create devices with rich physical and chemical properties. External periodic potentials can enable the manipulation of t…
Engineering Dirac states in graphene: Coexisting type-I and type-II Floquet-Dirac fermions
Hang Liu, Jia-Tao Sun, Sheng Meng
The coupling of monochromatic light fields and solids introduces nonequilibrium Floquet states, offering opportunities to create and explore new topological phenomena. Using combin…
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-…
Fermionic analogue of black hole radiation with a super high Hawking temperature
Hang Liu, Jia-Tao Sun, Huaqing Huang +2
Measurement of gravitational Hawking radiation of black hole (BH) is prohibitive because of an extremely low Hawking temperature (TH). Here we demonstrate a fermionic analog of BH…
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…
