Tunable magnetism in bilayer transition metal dichalcogenides
Li-Ya Qiao, Xiu-Cai Jiang, Ze Ruan +1
Twist between neighboring layers and variation of interlayer distance are two extra ways to control the physical properties of stacked two-dimensional van der Waals materials witho…
Site-selective insulating phase in twisted bilayer Hubbard model
Xiu-Cai Jiang, Ze Ruan, Yu-Zhong Zhang
The paramagnetic phase diagrams of the half-filled Hubbard model on a twisted bilayer square lattice are investigated using coherent potential approximation. Besides the convention…
Spontaneous charge-ordered state in Bernal-stacked bilayer graphene
Xiu-Cai Jiang, Ze-Yi Song, Ze Ruan +1
We propose that a weakly spontaneous charge-ordered insulating state probably exists in Bernal-stacked bilayer graphene which can account for experimentally observed non-monotonic…
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…
An improved particle swarm optimization algorithm and its application to search for new magnetic ground states in the Hubbard model
Ze Ruan, Xiu-Cai Jiang, Ze-Yi Song +1
An improved particle swarm optimization algorithm is proposed and its superiority over standard particle swarm optimization algorithm is tested on two typical benchmark functions.…
