Optical bulk-boundary dichotomy in a quantum spin Hall insulator
Junfeng Han, Pengcheng Mao, Hailong Chen +17
The bulk-boundary correspondence is a key concept in topological quantum materials. For instance, a quantum spin Hall insulator features a bulk insulating gap with gapless helical…

Ultralong carrier lifetime of topological edge states in a-Bi4Br4
Pengcheng Mao, Junfeng Han, Jingchuan Zheng +13
The rising of quantum spin Hall insulators (QSHI) in two-dimensional (2D) systems has been attracting significant interest in current research, for which the 1D helical edge states…

Observation of the Topologically Originated Edge States in large-gap Quasi-One-Dimensional a-BiBr
Pengcheng Mao, Maoyuan Wang, Dashuai Ma +16
Two-dimensional topological insulator features time-reversal-invariant spin-momentum-locked one-dimensional (1D) edge states with a linear energy dispersion. However, experimental…
