Differentiated roles of Lifshitz transition on thermodynamics and superconductivity in La2-xSrxCuO4
Yong Zhong, Zhuoyu Chen, Su-Di Chen +7
The effect of Lifshitz transition on thermodynamics and superconductivity in hole-doped cuprates has been heavily debated but remains an open question. In particular, an observed p…
Nematic fluctuations in the non-superconducting iron pnictide BaFeNiCrAs
Dongliang Gong, Ming Yi, Meng Wang +16
The main driven force of the electronic nematic phase in iron-based superconductors is still under debate. Here, we report a comprehensive study on the nematic fluctuations in a no…
Electronic structure of superconducting nickelates probed by resonant photoemission spectroscopy
Zhuoyu Chen, Motoki Osada, Danfeng Li +14
The discovery of infinite-layer nickelate superconductors has spurred enormous interest. While the Ni cations possess nominally the same 3 configuration as Cu in…
Flatband-Induced Itinerant Ferromagnetism in RbCoSe
Jianwei Huang, Zhicai Wang, Hongsheng Pang +8
CoSe (=K,Rb,Cs) is a homologue of the iron-based superconductor, FeSe. From a comprehensive study of RbCoSe via measurements of magnetization, tran…
Non-Thermal Emergence of an Orbital-Selective Mott Phase in FeTeSe
Jianwei Huang, Rong Yu, Zhijun Xu +15
Electronic correlation is of fundamental importance to high temperature superconductivity. Iron-based superconductors are believed to possess moderate correlation strength, which c…
Visualization of multifractal superconductivity in a two-dimensional transition metal dichalcogenide in the weak-disorder regime
Carmen Rubio-Verdú, Antonio M. García-García, Hyejin Ryu +8
Eigenstate multifractality is a distinctive feature of non-interacting disordered metals close to a metal-insulator transition, whose properties are expected to extend to supercond…
