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…

Charge-4 Weyl point: Minimum lattice model and chirality-dependent properties
Chaoxi Cui, Xiao-Ping Li, Da-Shuai Ma +2
Topological Weyl semimetals have been attracting broad interest. Recently, a new type of Weyl point with topological charge of , termed as charge-4 Weyl point (C-4 WP), was prop…

Double Dirac Nodal Line Semimetal with Torus Surface State
Xiao-Ping Li, Botao Fu, Da-Shuai Ma +3
We propose a class of nodal line semimetals that host an eight-fold degenerate double Dirac nodal line (DDNL) with negligible spin-orbit coupling. We find only 5 of the 230 space g…
