Itinerant Nature of Spin-Density-Wave Order in Ruddlesden-Popper Nickelates
Jiong Mei, Tianyang Xie, Kun Jiang
The nature of magnetism in layered Ruddlesden-Popper nickelates remains a central open question, particularly in light of recent observations of spin-wave-like magnetic excitations…
Frustration from Localized Zhang-Rice States: A Unified Theory of Doping-Driven Magnetic Transitions in Cuprates
Xiaodong Wang, Ping Xu, Jiong Mei +5
The microscopic mechanism by which doped holes disrupt the antiferromagnetic order is one of the fundamental questions in cuprates. In this work, we propose a unified microscopic t…
Orbital-Selective -wave Superconductivity in the Two-Band - Model: Possible Applications to LaNiO
Zhan Wang, Kun Jiang, Fu-Chun Zhang +1
We investigate superconductivity in a two-band - model consisting of an itinerant orbital (orbital-0) and a quasi-localized orbital (orbital-1) using variational Monte Carlo.…
Electronic structure of VSb kagome metals
Keyu Zeng, Zhan Wang, Kun Jiang +1
The kagome metals VSb ( K, Cs, Rb) have become a fascinating materials platform following the discovery of many novel quantum states due to the interplay between ele…
Self-doped Molecular Mott Insulator for Bilayer High-Temperature Superconducting La3Ni2O7
Zhan Wang, Heng-Jia Zhang, Kun Jiang +1
The bilayer structure of recently discovered high-temperature superconducting nickelates LaNiO provides a new platform for investigating correlation and superconductivi…
