A quantum geometric mechanism for chiral domain wall metastability: Application to twisted transition-metal dichalcogenides
Nisarg Chadha, Qiang Gao, Eslam Khalaf +1
Band topology can have an imprint on the excitations of a ferromagnet. A known example is quantum Hall ferromagnets and their lattice analogs; when both flavors have the same Chern…

Observation of metastable chiral domain walls in a topological magnet
Richen Xiong, Chenxin Qin, Zhaoyu Han +17
The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…

Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy
Woojoo Lee, Qiang Gao, Yufei Zhao +20
Quantum spin Hall insulators, or synonymously known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of thi…
