Tunable Polariton Canalization in Natural Van Der Waals Oxide

ABSTRACT Hyperbolic phonon polaritons (HPPs) are coupled oscillations of anisotropic lattice vibrations and electromagnetic fields that confine the latter to the nanoscale, enabling novel nano‐polaritonic devices. While HPPs have been identified in multiple layered materials, ach...

Flux-Driven Order–Disorder Polymorphs of KagomeSmFe6Ge6

Abstract While polymorphism in kagome-derived intermetallics offers a powerful route to controlling structure–property relationships, it still remains poorly explored for many rare-earth members due to synthetic constraints. Here, we report the discovery and controlled growth of...
