Second-Chern Bounds in Non-Abelian Quantum Geometry
Junwen Zhao, Zhiming Pan, Kang Yang +1
We study the quantum geometry of doubly degenerate energy levels in a four-dimensional parameter space. For degenerate pairs with gauge structures, the quantum geometry obe…
Emergent Interfacial Magnetism in Epitaxial RuO
Yudi Yang, Zhuang Qian, Shi Liu +1
The magnetic ground state of the altermagnet candidate RuO remains controversial, with magnetic signatures observed mainly in epitaxial films. Here we show, using first-princip…
Spin Quadrupolar orders in -wave Unconventional Magnetism
Jian-Keng Yuan, Zhiming Pan, Congjun Wu
Unconventional magnetism represents a class of metallic states whose Fermi surfaces exhibit spin-dependent splittings under the non-trivial representations of the rotation group. T…
Superconductivity in bilayer LaNiO: A review focusing on the strong-coupling Hund's rule assisted pairing mechanism
Zhiming Pan, Chen Lu, Fan Yang +1
Discovery of high- superconductivity (SC) in the bilayer nickelate series LaNiO have attracted substantial interest, providing a new platform for exploring unconve…
Possible Liquid-Nitrogen-Temperature Superconductivity Driven by Perpendicular Electric Field in the Single-Bilayer Film of LaNiO at Ambient Pressure
Zhi-Yan Shao, Jia-Heng Ji, Congjun Wu +2
Recently, high-temperature superconductivity (HTSC) is found in the LaNiO/SrLaAlO ultrathin film with critical temperature above the McMillan limit at ambient…
Strong-coupling study of the pairing mechanism in pressurized LaNiO
Jia-Heng Ji, Chen Lu, Zhi-Yan Shao +3
Recently, the bilayer perovskite nickelate LaNiO has been reported to exhibit high-temperature superconductivity near K under a moderate pressure of about GPa.…
