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…
Real-time observation of magnetization and magnon dynamics in a two-dimensional topological antiferromagnet MnBi2Te4
F. Michael Bartram, Meng Li, Liangyang Liu +9
Atomically thin van der Waals magnetic materials have not only provided a fertile playground to explore basic physics in the two-dimensional (2D) limit but also created vast opport…
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…
Evolution of the electronic structure of ultrathin MnBi2Te4 Films
Runzhe Xu, Yunhe Bai, Jingsong Zhou +18
Ultrathin films of intrinsic magnetic topological insulator MnBi2Te4 exhibit fascinating quantum properties such as quantum anomalous Hall effect and axion insulator state. In this…
Ultrafast coherent interlayer phonon dynamics in atomically thin layers of MnBi2Te4
F. Michael Bartram, Yu-Chen Leng, Yongchao Wang +10
The atomically thin MnBi2Te4 crystal is a novel magnetic topological insulator, exhibiting exotic quantum physics. Here we report a systematic investigation of ultrafast carrier dy…
