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…
Three-Dimensional Electronic Structures in Superconducting Ruddlesden-Popper Bilayer Nickelate Films
Yueying Li, Lizhi Xu, Wei Lv +13
Beyond the quasi-two-dimensional (2D) paradigm of cuprates, the role of the third dimension of the Ruddlesden-Popper bilayer nickelates is essential to decoding their superconducti…
Multimodal Terahertz Spectroscopy of the Pairing Symmetry and Normal-State Pseudogap in (La,Pr)NiO Films
Shuxiang Xu, Guangdi Zhou, Hao Wang +11
The discovery of ambient-pressure superconductivity in compressively strained (La,Pr)NiO thin films has intensified efforts to identify the pairing mechanism. However,…
Pressure-enhanced superconductivity and its correlation with suppressed resistance dip in (La,Pr)3Ni2O7 films
Jinyu Zhao, Guangdi Zhou, Shu Cai +11
The discovery of superconductivity with a transition temperature (Tc) exceeding 40 K in La3Ni2O7 and (La,Pr)3Ni2O7 thin films at ambient pressure provides a viable platform for the…
Superconductivity onset above 60 K in ambient-pressure nickelate films
Guangdi Zhou, Heng Wang, Haoliang Huang +7
Ambient-pressure superconductivity in nickelates has been capped at an onset transition temperature () of ~50 K, a value that remains lower than the cuprate (~133 K)…
Intertwined Charge Stripes and Majorana Zero Modes in An Iron-Based Superconductor
Yu Liu, Li-Xuan Wei, Qiang-Jun Cheng +12
In type-II superconductors, magnetic fields modulate the amplitude and phase of the superconducting order parameter, forming quantized vortices where superconductivity is locally s…
