Signatures of quantum chaos in phonon-polariton billiards
Yinan Dong, Felix Liu, Ekrem Demirboga +11
We use scanning near-field optical microscopy to image hyperbolic phonon polaritons in hexagonal boron nitride (hBN) billiards with integrable and chaotic geometries. In Sinai bill…

Fröhlich-type Polarons in Isotopically Enriched Hexagonal Boron Nitride
Ioannis Chatzakis, Timur Abdilov, Elliot Walker +3
Exciton-phonon interactions play a central role in defining the optical response of hexagonal boron nitride (hBN), yet their quantitative determination has remained incomplete. Her…
