Helical Luttinger liquid on the edge of a 2-dimensional topological antiferromagnet
Yang Feng, Jinjiang Zhu, Weiyan Lin +12
Boundary helical Luttinger liquid (HLL) with broken bulk time-reversal symmetry belongs to a unique topological class which may occur in antiferromagnets (AFM). Here, we search for…
Quantized anomalous Hall resistivity achieved in molecular beam epitaxy-grown MnBi2Te4 thin films
Yunhe Bai, Yuanzhao Li, Jianli Luan +17
The intrinsic magnetic topological insulator MnBi2Te4 provides a feasible pathway to high temperature quantum anomalous Hall (QAH) effect as well as various novel topological quant…
Direct visualization of percolating metal-insulator transition in V2O3 using scanning microwave impedance microscopy
Weiyan Lin, Huanyu Zhang, Yoav Kalcheim +9
Using the extensively studied V2O3 as a prototype system, we investigate the role of percolation in metal-insulator transition (MIT). We apply scanning microwave impedance microsco…
Influences of the dissipative topological edge state on quantized transport in MnBi2Te4
Weiyan Lin, Yang Feng, Yongchao Wang +9
The beauty of quantum Hall (QH) effect is the metrological precision of Hall resistance quantization that originates from the topological edge states. Understanding the factors tha…
