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…
Anomalous Nodal Gap in a Doped Spin-1/2 Antiferromagnetic Mott Insulator
Yong Hu, Christopher Lane, Xiang Chen +10
Many emergent phenomena appear in doped Mott insulators near the insulator-to-metal transition. In high-temperature cuprate superconductors, superconductivity arises when antiferro…
Lorentz Skew Scattering Nonreciprocal Magneto-Transport
Xiu Fang Lu, Xue-Jin Zhang, Naizhou Wang +9
In materials with broken inversion symmetry, nonreciprocal magneto-transport (NRMT) manifests as a bilinear dependence of charge conductivity on applied electric (E) and magnetic (…
Soft Phonon Charge-Density Wave Formation in the Kagome Metal KVSb
Yifan Wang, Chenchao Xu, Zhimian Wu +11
A range of of unusual emergent behaviors have been reported in the charge-density wave (CDW) state of the VSb (K, Rb, Cs) kagome metals, including a CDW formation p…
