Claims

C1strongest claim

By interfacing distinct Dirac photonic crystals that host Dirac cones at different high-symmetry points (Γ and K) and carefully engineering the boundary conditions, the boundary-induced CABSs in adjacent channels become effectively decoupled due to a large momentum separation, thereby eliminating inter-channel crosstalk, with experimental robustness to metallic obstacles, air defects, and sharp bends.

C2weakest assumption

The large momentum separation between CABSs originating from Γ and K points is assumed to be sufficient to prevent any residual coupling or scattering at the engineered interfaces and boundaries without additional losses or mode mixing.

C3one line summary

Demonstration of momentum-decoupled chiral anomaly bulk states enabling crosstalk-free, cladding-free waveguide arrays in photonic crystals with experimental robustness to defects and extension to 2D resonators and crossings.
