Realization of Spin‐locked Acoustic Helical Landau Levels in both Hexagonal and Square Lattices

open access: yesAdvanced Science, EarlyView.
Acoustic helical Landau levels rooted in quantum spin Hall systems are achieved by linearly increasing the local bandgap through the lifting of the double Dirac cone in acoustic crystals. Large‐area conveyance of acoustic energy facilitated by these helical Landau levels is demonstrated.

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.

3D Topological Inorganic Electrides: Screening, Properties, and Applications

open access: yesAdvanced Science, EarlyView.
In inorganic electrides, zero‐, one‐, and two‐dimensional (0D, 1D, and 2D) interstitial anionic electrons interconnect within lattice cavities, collectively forming a three‐dimensional (3D) network, further coupling magnetism and topological features, leading to the emergence of 3D topological inorganic electrides.
