Superconductivity, pseudogap and marginal Fermi liquid in a relative-momentum-local theory
Jian-Jian Miao
Cuprate superconductors host \(d\)-wave superconductivity (SC), a pseudogap (PG) with Fermi arcs and a strange metal (SM) with incoherent excitations and temperature-linear resisti…
Hall Coefficient Sign Reversal Driven by Orbital-Selective Oxygen-Vacancy Scattering in Nickelate Films
Jian-Jian Miao, Yue Liu, Yue Zhao +3
Hall measurements in superconducting bilayer nickelate films show sign reversals that cannot be explained by rigid-band electron doping alone. We combine a DFT+CDMFT-derived correl…
Possible Enhancement of Superconductivity in Ambient-Pressure LaNiO Thin Film
Yichen Hua, Wenxin He, Wei-Qiang Chen +2
As an unconventional superconducting system capable of reaching 60 K under ambient pressure, the LaNiO thin film superconductor has recently become a focal point in the…
Atomically resolved intrinsic superconducting gap in (La,Pr)3Ni2O7 films
Xinxin Wang, Yaqi Chen, Cui Ding +7
Ruddlesden-Popper bilayer nickelates provide an emerging platform for studying high-temperature superconductivity, yet the superconducting pairing symmetry remains under debate. He…
Correlated electronic structures and unconventional superconductivity in bilayer nickelate heterostructures
Changming Yue, Jian-Jian Miao, Haoliang Huang +12
The recent discovery of ambient-pressure superconductivity in thin-film bilayer nickelates opens new possibilities for investigating electronic structures in this new class of high…
