Two-dimensional Obstructed Atomic Insulators with Fractional Corner Charge in MAZ Family
Lei Wang, Yi Jiang, Jiaxi Liu +6
According to topological quantum chemistry, a class of electronic materials have been called obstructed atomic insulators (OAIs), in which a portion of valence electrons necessaril…
Structure effect on intrinsic piezoelectricity in septuple-atomic-layer (M=Mo and W)
San-Dong Guo, Yu-Tong Zhu, Wen-Qi Mu +2
The recently experimentally synthesized monolayer and (\textcolor[rgb]{0.00,0.00,1.00}{Science 369, 670-674 (2020})) lack inversion symmetr…
Structure-driven intercalated architecture of septuple-atomic-layer family with diverse properties from semiconductor to topological insulator to Ising superconductor
Lei Wang, Yongpeng Shi, Mingfeng Liu +8
Motivated by the fact that septuple-atomic-layer MnBiTe can be structurally viewed as the combination of double-atomic-layer MnTe intercalating into quintuple-atomic-layer…
Computation and data driven discovery of topological phononic materials
Jiangxu Li, Jiaxi Liu, Stanley A. Baronett +4
The discovery of topological quantum states marks a new chapter in both condensed matter physics and materials sciences. By analogy to spin electronic system, topological concepts…
Underlying topological Dirac nodal line mechanism of anomalously large electron-phonon coupling strength on Be (0001) surface
Ronghan Li, Jiangxu Li, Lei Wang +4
Beryllium was recently discovered to harbor a Dirac nodal line (DNL) in its bulk phase and the DNL-induced non-trivial drumhead-like surface states (DNSSs) on its (0001) surface, r…
Topological Weyl-like Phonons and Nodal Line Phonons in Graphene
Jiangxu Li, Lei Wang, Jiaxi Liu +3
By means of first-principles calculations and modeling analysis, we have predicted that the traditional 2D-graphene hosts the topological phononic Weyl-like points (PWs) and phonon…
