For more than seven decades, hexagonal boron nitride (hBN) has been employed as an
inert, thermally stable engineering ceramic; since 2010, it has also been used as the optimal …

Anisotropic planar polaritons-hybrid electromagnetic modes mediated by phonons,
plasmons, or excitons-in biaxial two-dimensional (2D) van der Waals crystals have attracted …

Moiré engineering is being intensively investigated as a method to tune the electronic,
magnetic and optical properties of twisted van der Waals materials. Advances in moiré …

The lattice symmetry of a crystal is one of the most important factors in determining its
physical properties. Particularly, low-symmetry crystals offer powerful opportunities to control …

The coupled interactions among the fundamental carriers of charge, heat, and
electromagnetic fields at interfaces and boundaries give rise to energetic processes that …

The biaxial van der Waals semiconductor α‐phase molybdenum trioxide (α‐MoO3) has
recently received significant attention due to its ability to support highly anisotropic phonon …

Here, we review the progress and most recent advances in phonon-polaritonics, an
emerging and growing field that has brought about a range of powerful possibilities for mid …

A hyperbolic plasmonic surface supports highly directional propagating polaritons with
extremely large density of states. Such plasmon polaritons have been realized in artificially …

Strong coupling between optical modes can be implemented into nanophotonic design to
modify the energy–momentum dispersion relation. This approach offers potential avenues …

Hyperbolic phonon polaritons (HPhPs) are generated when infrared photons couple to polar
optic phonons in anisotropic media, confining long-wavelength light to nanoscale volumes …
