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…

Destructive interference of second harmonic generation in AA stacked MoTe/WSe
Yiduo Wang, Yao Lu, Changshen Chen +14
The stacking configuration of two-dimensional materials critically governs their optical and electronic responses. Monolayer transition-metal dichalcogenides (TMDC) lack inversion…

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…
