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…
Ultrafast decoupling of the pseudogap from superconductivity in a pressurized cuprate
Yanghao Meng, Wenjin Mao, Liucheng Chen +7
The relationship between the pseudogap and superconductivity remains a central puzzle in the physics of cuprates. Hydrostatic pressure provides a clean tuning parameter free from c…
Superconducting phase interference effect in momentum space
Bo Zhan, Qiang Gao, Runze Chi +5
Detecting the phases of the superconducting order parameter is pivotal for unraveling the pairing symmetry of superconducting electrons. Conventional methods for probing these phas…
Neutron Spin Resonance Near a Lifshitz Transition in Overdoped BaKFeAs
Yang Li, Dingsong Wu, Yingjie Shu +11
Elucidating the relationship between spin excitations and fermiology is essential for clarifying the pairing mechanism in iron-based superconductors (FeSCs). Here, we report inelas…
Dominant apical-oxygen electron-phonon coupling in HgBaCaCuO
Wenshan Hong, Qizhi Li, Shilong Zhang +14
How electron-phonon interactions influence high-temperature superconductivity in cuprates remains contested, and their role outside the CuO planes has been largely overlooked.…
Spectroscopic origin of giant anomalous Hall effect in an interwoven magnetic kagome metal
Erjian Cheng, Kaipu Wang, Yiqing Hao +20
The discovery of a giant anomalous Hall effect (AHE) and its novel mechanism holds significant promise for advancing both fundamental research and practical applications. Magnetic…
