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…

Probing the Linewidth of the 12.4-keV Sc Isomeric Resonance in Solids by Nuclear Forward Scattering
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc transition from the nuclear ground state to the 12.389-keV isomer (lifetime 0.46~s) has an ultranarrow natural linewidth $Γ_{\ind{0}}\simeq 1.4$~feV, corresponding to…
