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.

BiSbF2 Monolayer: A 2D Inversion‐Asymmetric Topological Insulator With Linearly Tunable Giant Spin‐Splitting and Bulk Gap

open access: yesAdvanced Electronic Materials, EarlyView.
The BiSbF2 monolayer is a 2D topological insulator with a large bandgap (252 meV) hosting topological edge states and giant valley‐contrasted spin‐splitting (478 meV). The sizable gap enables room‐temperature quantum spin Hall effects, while its coexisting topological and valleytronic features provide a versatile platform for exploring topological ...
