Rotation topological states: theory and material realization
Chun-Xue Liu, Yilin Han, Runze Li +2
The paper introduces a rotation‑subspace topological invariant (a Z₂ⁿ invariant) that reveals hidden topological phases in materials with rotational symmetry, and demonstrates its…

Anomalous shift in scattering from topological nodal-ring semimetals
Runze Li, Chaoxi Cui, Ying Liu +2
An electron beam may experience an anomalous spatial shift during an interface scattering process. Here, we investigate this phenomenon for reflection from mirror-symmetry-protecte…
