Tunable band gap in twisted bilayer graphene
Xiu-Cai Jiang, Yi-Yuan Zhao, Yu-Zhong Zhang
At large commensurate angles, twisted bilayer graphene which holds even parity under sublattice exchange exhibits a tiny gap. Here, we point out a way to tune this tiny gap into a…
Uncovering double-stripe and plaquette antiferromagnetic states in the one-band Hubbard model on a frustrated square lattice
Ze Ruan, Xiu-Cai Jiang, Ze-Yi Song +1
Groundstate magnetism of the one-band Hubbard model on the frustrated square lattice where both nearest-neighbour and next-nearest-neighbour hoppings are considered at…
Breakdown of the Hund's Rule in CuFeAs
Ze-Yi Song, Xiu-Cai Jiang, Xiao-Fang Ouyang +1
The ground-state properties of CuFeAs were investigated by applying density functional theory calculations within generalized gradient approximation (GGA) and GGA+U. We find that t…
Orbitally-selective Breakdown of the Fermi Liquid and Simultaneous Enhancement of Metallic and Insulating States in Correlated Multi-band Systems with Spin-orbit Coupling
Ze-Yi Song, Xiu-Cai Jiang, Yu-Zhong Zhang
We show that spin-orbit coupling (SOC) plays Janus-faced roles on the orbitally-selective Mott transitions in a three-orbital Hubbard model with crystal field splitting at a specif…
Distinct Nature of Orbital Selective Mott Phases Dominated by the Low-energy Local Spin Fluctuations
Ze-Yi Song, Xiu-Cai Jiang, Hai-Qing Lin +1
Quantum orbital selective Mott (OSM) transitions are investigated within dynamical mean-field theory based on a two-orbital Hubbard model with different bandwidth at half filling.…
Fully Spin-Polarized Current in Gated Bilayer Silicene
Xiao-Fang Ouyang, Ze-Yi Song, Yu-Zhong Zhang
By applying density functional theory calculations, we predict that the groundstate of bilayer silicene at certain interlayer distances can be antiferromagnetic. At small electron…
