Discovery of d-orbital order in Tb2CoAl4Ge2
Zhanyang Hao, Haohao Sheng, Wanru Ma +32
Orbital order describes a quantum state where occupied orbitals line up in a periodic pattern. While orbital physics plays a fundamental and universal role in strongly correlated e…
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…
