Thickness-driven crossover from conventional to chiral nonreciprocal superconductivity in kagome metal CsV3Sb5
Wei Zhang, Jiangbo Luo, Nikolai Peshcherenko +10
Superconductivity and its potential applications are governed by the symmetry of the superconducting order parameter. In the kagome metal CsV3Sb5, most bulk studies indicate conven…
Anomalous Low-temperature Magnetotransport in Kagome Metal CsCrSb under Pressure
Zikai Zhou, Wenyan Wang, Deng Hu +5
As a unique kagome superconductor displaying clear signatures of strong electronic correlations, CsCrSb has drawn much attention. Its rich temperature-pressure phase diagra…
Giant critical current peak induced by pressure in kagome superconductor RbVSb
Lingfei Wang, Wenyan Wang, Tsz Fung Poon +11
Superconductivity can coexist or compete with other orders such as magnetism or density waves. Optimizing superconductivity requires identifying competing orders that may disrupt C…
Point-contact Andreev reflection spectroscopy of layered superconductors with device-integrated diamond anvil cells
Che-hsuan Ku, Omargeldi Atanov, King Yau Yip +9
Superconductors that can be mechanically exfoliated are an interesting platform for exploring superconducting properties tuned by layer thickness. These layered superconductors are…
Superconducting critical temperature and dimensionality tuning of RbVSb via biaxial strain
Tsz Fung Poon, King Yau Yip, Ying Kit Tsui +10
Kagome metal AVSb (A=K, Rb, Cs) has emerged as an intriguing platform for exploring the interplay between superconductivity and other quantum states. Among the three compou…
Discovery of a new phase in thin flakes of KVSb under pressure
Zheyu Wang, Lingfei Wang, King Yau Yip +13
We report results of magnetotransport measurements on KVSb thin flakes under pressure. Our zero-field electrical resistance reveals an additional anomaly emerging under pre…
