Persistent Fermi Pockets and Robust Electron Pairing in Lightly Doped CuO Planes of Cuprate Superconductors
Hao Chen, Jumin Shi, Yinghao Li +23
High temperature superconductivity in cuprate superconductors is generally considered to be generated from doping the Mott insulators. The fundamental nature of the doped parent co…
Impact of Electron Correlations on Infinite-Layer Cuprates and Nickelates
Xunyang Hong, Yuetong Wu, Ying Chan +18
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
Persistent paramagnons in high-temperature infinite-layer nickelate superconductors
Yujie Yan, Ying Chan, Xunyang Hong +25
The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
Absence of BCS-BEC Crossover in FeSe0.45Te0 55 Superconductor
Junjie Jia, Yadong Gu, Chaohui Yin +21
In iron-based superconductor Fe(Se,Te), a flat band-like feature near the Fermi level was observed around the Brillouin zone center in the superconducting state. It is under debate…
Discovery of Giant Unit-Cell Super-Structure in the Infinite-Layer Nickelate PrNiO
J. Oppliger, J. Küspert, A. -C. Dippel +10
Spectacular quantum phenomena such as superconductivity often emerge in flat-band systems where Coulomb interactions overpower electron kinetics. Engineering strategies for flat-ba…
