Enhanced and robust superconductivity in La0.8Sr0.2NiO2 membranes compressed up to 210 GPa
Shu Cai, Yuqing Tian, Shengjun Yan +10
The discovery of superconductivity in infinite-layer nickelate thin films has opened a new frontier for exploring unconventional oxide superconductors beyond the copper oxide famil…
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…
T-linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu2(BO3)2
Jing Guo, Pengyu Wang, Cheng Huang +13
The pressurized Shastry-Sutherland Mott insulator SrCu2(BO3)2 has been found to host a plaquette-singlet phase and an antiferromagnetic phase that break different symmetries sponta…
Signatures of a Lifshitz transition in pressurized electron-doped cuprate
Jinyu Zhao, Shu Cai, Zhaoyu Liu +14
It is well known that the electronic structure of hole-doped cuprate superconductors is tunable through both chemical doping and external pressure, which frequently offer us new in…
Superconducting susceptibility signal captured in a record wide pressure range
Shu Cai, Jinyu Zhao, Di Peng +11
In recent years, the resistance signature of the high temperature superconductivity above 250 K in highly compressed hydrides (more than 100 GPa) has garnered significant attention…
Superconducting-transition-temperature dependence of superfluid density and conductivity in pressurized cuprate superconductors
Jinyu Zhao, Shu Cai, Yiwen Chen +15
What factors fundamentally determine the value of superconducting transition temperature (Tc) in high temperature superconductors has been the subject of intense debate. Following…
