An important goal of modern condensed-matter physics involves the search for states of
matter with emergent properties and desirable functionalities. Although the tools for material …

The coherent exchange of energy between materials and optical fields leads to strong light–
matter interactions and so-called polaritonic states with intriguing properties, halfway …

Lead-halide perovskites are generally excellent light emitters and can have larger exciton
binding energies than thermal energy at room temperature, exhibiting great promise for …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Topological insulators—materials that are insulating in the bulk but allow electrons to flow
on their surface—are striking examples of materials in which topological invariants are …

Bound states in the continuum (BICs),–are peculiar topological states that, when realized in
a planar photonic crystal lattice, are symmetry-protected from radiating in the far field despite …

Monolayer transition-metal dichalcogenide (TMD) materials have attracted a great attention
because of their unique properties and promising applications in integrated optoelectronic …

Quantum mechanical interactions between electromagnetic radiation and matter underlie a
broad spectrum of optical phenomena. Strong light-matter interactions result in the well …

We report the first observation of the magnon-polariton bistability in a cavity magnonics
system consisting of cavity photons strongly interacting with the magnons in a small yttrium …

Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …
