Shear-stress-constrained superconductivity in Ruddlesden-Popper nickelates
Liling Sun, Shu Cai, Jinyu Zhao +4
Ruddlesden-Popper nickelates exhibit superconductivity under pressure in bulk crystals and under epitaxial constraint in thin films, while remaining highly sensitive to sample qual…

Superconductivity Favored Anisotropic Phase Stiffness in Infinite-Layer Nickelates
Minyi Xu, Dong Qiu, Minghui Xu +10
In unconventional superconductors such as cuprates and iron pnictides and chalcogenides, phase stiffness - a measure of the energy cost associated with superconducting phase variat…

Correlation between unconventional superconductivity and strange metallicity revealed by operando superfluid density measurements
Ruozhou Zhang, Mingyang Qin, Chenyuan Li +15
Strange-metal behavior has been observed in superconductors ranging from cuprates to pressurized nickelates, but its relationship to unconventional superconductivity remains elusiv…
