Abstract

Polaritons in van der Waals (vdW) materials.Polaritons-a hybrid of light-matter oscillations-can originate in different physical phenomena: conduction electrons in graphene and topological insulators (surface plasmon polaritons), infrared-active phonons in boron nitride (phonon polaritons), excitons in dichalcogenide materials (exciton polaritons), superfluidity in FeSe-and Cu-based superconductors with high critical temperature T c (Cooper-pair polaritons), and magnetic resonances (magnon polaritons).The family of vdW materials supports all of these polaritons.The matter oscillation component results in negative permittivity (e B < 0) of the polaritonic material, giving rise to optical-field confinement at the interface with a positive-permittivity (e A > 0) environment.vdW polaritons exhibit strong confinement, as defined by the ratio of incident light wavelength l 0 to polariton wavelength l p .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
