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…
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…
Charge stripe and superconductivity tuned by interlayer interaction in a sign-problem-free bilayer extended Hubbard model
Runyu Ma, Zenghui Fan, Hongxin Liu +2
Competing orders represent a central challenge in understanding strongly correlated systems. In this work, we employ projector quantum Monte Carlo simulations to study a sign-probl…
Comparison of superconducting pairing in doped cuprates and nickelates within an extended Hubbard model
Yicheng Xiong, Hang Ma, Hongxing Liu +2
Within a Hubbard model, we investigate the superconducting pairing behavior of infinite-layer nickelate and cuprate superconductors by using the determinant quan…
