Tuning superconductivity and charge density wave order by next-nearest-neighbor hopping integral in honeycomb Holstein model
Hongxing Liu, Lufeng Zhang, Tianxing Ma
By using unbiased determinant quantum Monte Carlo simulations, we investigate the interplay between superconductivity and charge density wave order in the Holstein model on a honey…
Magnetic fluctuations near the Van Hove singularity in the kagome-lattice Hubbard model at finite doping
Jingyao Wang, Zixuan Jia, Zenghui Fan +2
The kagome-lattice Hubbard model attracts widespread interest due to its flat-band and Van Hove singularity features, which can give rise to unconventional magnetism. We employ det…
Precompression engineering of metal-insulator transition and magnetism in designed breathing kagome systems
Qingzhuo Duan, Hongdao Zhuge, Ying Liang +1
Kagome materials featuring dispersive Dirac cones and topological flat bands exhibit unique electronic and magnetic properties. However, kagome compounds with tunable electrical co…
Strain-enhanced edge ferromagnetism and bipolar magnetic semiconducting behavior in Janus graphene nanoribbons
Ran Liu, Hongxing Liu, Junfeng Ren +1
Using first-principles density functional theory and determinant quantum Monte Carlo methods, we show that Janus graphene nanoribbons with topological defect arrays () exhibit…
Novel dynamical excitations and roton-based measurement of Cooper-pair momentum in a two-dimensional Fulde-Ferrell-Larkin-Ovchinnikov superfluid on optical lattices
Shuning Tan, Jiayi Shi, Peng Zou +2
Determining the center-of-mass (COM) momentum of Cooper pairs in unconventional superconductors or superfluids is a topic of great interest in condensed matter physics and ultracol…
