Transverse hypercrystals formed by periodically modulated phonon-polaritons
Hanan Herzig Sheinfux, Minwoo Jung, Lorenzo Orsini +10
Photonic crystals and metamaterials are two overarching paradigms for manipulating light. Combining the two approaches leads to hypercrystals: hyperbolic dispersion metamaterials t…
Thickness and twist angle dependent interlayer excitons in metal monochalcogenide heterostructures
Wenkai Zheng, Li Xiang, Felipe de Quesada +18
Interlayer excitons, or bound electron-hole pairs whose constituent quasiparticles are located in distinct stacked semiconducting layers, are being intensively studied in heterobil…
Negative refraction in hyperbolic hetero-bicrystals
A. J. Sternbach, S. L. Moore, A. Rikhter +12
We visualized negative refraction of phonon polaritons, which occurs at the interface between two natural crystals. The polaritons - hybrids of infrared photons and lattice vibrati…
Magnetic imaging with spin defects in hexagonal boron nitride
P. Kumar, F. Fabre, A. Durand +13
Optically-active spin defects hosted in hexagonal boron nitride (hBN) are promising candidates for the development of a two-dimensional (2D) quantum sensing unit. Here, we demonstr…
Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
High quality nanocavities through multimodal confinement of hyperbolic polaritons in hexagonal boron nitride
Hanan Herzig Sheinfux, Lorenzo Orsini, Minwoo Jung +15
A conventional optical cavity supports modes which are confined because they are unable to leak out of the cavity. Bound state in continuum (BIC) cavities are an unconventional alt…
