Phononic Obstructed Atomic Insulators with Robust Corner Modes
Da-Shuai Ma, Kejun Yu, Xiao-Ping Li +2
Higher-order topological insulators (HOTIs) are described by symmetric exponentially decayed Wannier functions at some unoccupied Wyckoff positions and classified as ob…
Anomalous skew-scattering nonlinear Hall effect and chiral photocurrents in {\it PT}-symmetric antiferromagnets
Da Ma, Arpit Arora, Giovanni Vignale +1
Berry curvature and skew-scattering play central roles in determining both the linear and nonlinear anomalous Hall effects. Yet in {\it PT}-symmetric antiferromagnetic metals, Hall…
Inventory of high-quality flat-band van der Waals materials
Jingyi Duan, Da-Shuai Ma, Run-Wu Zhang +5
More is left to do in the field of flat bands besides proposing theoretical models. One unexplored area is the flat bands featured in the van der Waals (vdW) materials. Exploring m…
Quantum transport evidence of the boundary states and Lifshitz transition in BiBr
Dong-Yun Chen, Dashuai Ma, Junxi Duan +4
The quasi-one-dimensional van der Waals compound BiBr was recently found to be a promising high-order topological insulator with exotic electronic states. In this paper, we…
