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…
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…
Atomic-scale spin sensing of a 2D -wave altermagnet via helical tunneling
Zhuying Wang, Shuikang Yu, Xingkai Cheng +17
Altermagnetism simultaneously possesses nonrelativistic spin responses and zero net magnetization, thus combining advantages of ferromagnetism and antiferromagnetism. This superior…
Observation of robust one-dimensional edge channels in a three-dimensional quantum spin Hall insulator
Shuikang Yu, Junze Deng, Wenhao Liu +13
Topologically protected edge channels show prospects for quantum devices. They have been found experimentally in two-dimensional (2D) quantum spin Hall insulators (QSHIs), weak top…
Nanoscale determination of the metal-insulator transition in intercalated bulk VSe
Wanru Ma, Ye Yang, Zuowei Liang +4
Two-dimensional (2D) materials provide unique opportunities to realize emergent phenomena by reducing dimensionality. Using scanning tunneling microscopy combined with first-princi…
Electronic-correlation-assisted charge stripe order in a Kagome superconductor
Linwei Huai, Zhuying Wang, Huachen Rao +12
A central mystery in high-temperature cuprate superconductors is the coexistence of multiple exotic orders, which is presumably associated with strong electronic correlation. The o…
