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…
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…
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…
