Ferroelectric higher-order topological insulator in two dimensions
Ning Mao, Runhan Li, Xiaorong Zou +3
The interplay between ferroelectricity and band topology can give rise to a wide range of both fundamental and applied research. Here, we map out the emergence of nontrivial corner…

Orbital shift-induced boundary obstructed topological materials with a large energy gap
Ning Mao, Runhan Li, Ying Dai +3
We propose boundary obstructed topological phases caused by Wannier orbital shift between ordinary atomic sites, which, however, cannot be indicated by symmetry eigenvalues at high…

Doubled Quantum Spin Hall Effect with High-Spin Chern Number in -Antimonene and -Bismuthene
Yingxi Bai, Linke Cai, Ning Mao +4
The discovery of quantum spin Hall effect has ignited the field of topological physics with vast variety of exotic properties. Here, we present the emergence of doubled quantum spi…
