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…
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…
Unveiling the landscape of Mottness and its proximity to superconductivity in 4Hb-TaS
Ping Wu, Zhuying Wang, Yunmei Zhang +15
Mott physics is at the root of a plethora of many-body quantum phenomena in quantum materials. Recently, the stacked or twisted structures of van der Waals (vdW) materials have eme…
