Direct observation of chiral edge current at zero magnetic field in odd-layer MnBiTe
Jinjiang Zhu, Yang Feng, Xiaodong Zhou +14
The chiral edge current is the boundary manifestation of the Chern number of a quantum anomalous Hall (QAH) insulator. Its direct observation is assumed to require well-quantized H…
Fabrication-induced even-odd discrepancy of magnetotransport in few-layer MnBiTe
Yaoxin Li, Yongchao Wang, Zichen Lian +20
The van der Waals antiferromagnetic topological insulator MnBi2Te4 represents a promising platform for exploring the layer-dependent magnetism and topological states of matter. Rec…
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…
Magnetization-tuned topological quantum phase transition in MnBi2Te4 devices
Jun Ge, Yanzhao Liu, Pinyuan Wang +7
Recently, the intrinsic magnetic topological insulator MnBi2Te4 has attracted enormous research interest due to the great success in realizing exotic topological quantum states, su…
Direct visualization of edge state in even-layer MnBi2Te4 at zero magnetic field
Weiyan Lin, Yang Feng, Yongchao Wang +12
Being the first intrinsic antiferromagnetic(AFM) topological insulator(TI), MnBi2Te4 is argued to be a topological axion state in its even-layer form due to the antiparallel magnet…
