Thermodynamic phase transition, pairing symmetry and Fermi surface topology in Ruddlesden-Popper nickelate films
Yu Miao, Zhiwei Wang, Hongxu Sun +9
Ruddlesden-Popper (RP) nickelates provide an uncharted territory to explore high-transition-temperature (high-) superconductivity and superconducting mechanism. Here, we inves…
Electron-like high-temperature superconductivity induced by compressive strain in La2PrNi2O7 thin films
Zhiwei Wang, Zhengjie Wang, Huiyu Wang +8
The realization of high-temperature superconductivity in bilayer nickelates under epitaxial compressive strain is widely interpreted as mimicking the effects of high hydrostatic pr…
Discovery of d-orbital order in Tb2CoAl4Ge2
Zhanyang Hao, Haohao Sheng, Wanru Ma +32
Orbital order describes a quantum state where occupied orbitals line up in a periodic pattern. While orbital physics plays a fundamental and universal role in strongly correlated e…
Cascade of magnetic-field-induced quantum spin states in a spin-1 honeycomb magnet
Kaixin Tang, Zhao-Yang Dong, Yanyan Shangguan +10
Quantum fluctuations endow spin systems with surprisingly enriched magnetic phase diagrams. In frustrated magnets, strong quantum fluctuations boosted by either geometrical incompa…
ac strain based thermodynamic criterion for vortex lattice in type-II superconductors
Peipei Lu, Mengju Yuan, Jing Zhang +17
In type-I superconductors, zero electrical resistivity and perfect diamagnetism define two fundamental criteria for superconducting behavior. In contrast, type-II superconductors e…
Visualizing the interplay of dual electronic nematicities in kagome superconductors
Yunmei Zhang, Jun Zhan, Ping Wu +15
Kagome superconductor AVSb (A stands for K, Rb, and Cs) hosts a wealth of intertwined electronic orders driven by geometric frustration and electron correlations. Among the…
