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…
Orbital-Selective Diagonal-Gap Test of Pairing in LaNiO
Yu-Bo Liu, Zhi-Yan Shao, Zhiming Pan +2
Recent angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) measurements on bilayer nickelate LaNiO reveal a nearly isotropic, node…
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…
Charge-4e/6e superconductivity and chiral metal from 3D chiral superconductor
Chu-Tian Gao, Chen Lu, Yu-Bo Liu +2
Unconventional superconductivity (SC) characterized by multi-fermion orderings has attracted substantial attention. However, previous studies have largely focused on 2D systems or…
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.…
