Abstract

Photonic crystals built with time-reversal-symmetry-breaking Faraday-effect media can exhibit chiral edge modes that propagate unidirectionally along boundaries across which the Faraday axis reverses. These modes are precise analogs of the electronic edge states of quantum-Hall-effect (QHE) systems, and are also immune to backscattering and localization by disorder. The Berry curvature of the photonic bands plays a role analogous to that of the magnetic field in the QHE. Explicit calculations demonstrating the existence of such unidirectionally propagating photonic edge states are presented.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The centre-of-energy velocity of the wave packet contains an anomalous contribution proportional to the Berry curvature of the band, and this contribution is responsible for various Hall effects.

    “Based on the semi-classic equations of motion for wave packet propagation in the presence of Berry curvature1,19,20,33,34, the centre-of-energy velocity of the wave packet contains an ‘anomalous’ contribution proportional to the Berry curvature of the band, and this contribution is responsible for various Hall effects1,19,33.”

    From Photonic Hall effect and helical Zitterbewegung in a synthetic Weyl system (2019) · cites this paper as [19]

    The Introduction (p. 1) states that Berry curvature adds an anomalous contribution to wavepacket velocity and links that velocity to the anomalous Hall effect. But it specifies that the contribution is proportional to acceleration; §D (p. 7) says it is active only when the wavepacket is accelerated by an inhomogeneous medium. The copy does not establish that this velocity contribution is responsible for Hall effects generally. (LLM, conf=0.82)

  • Since pioneering theoretical predictions and experimental demonstrations of topologically protected electromagnetic edge states, most studies have focused on linear topological photonic structures.

    “Since the pioneering theoretical predictions [100] and experimental demonstrations [101] of topologically protected electromagnetic edge states, most studies have focused on linear topological photonic structures [75,21].”
  • The spin-orbit interaction of light and spin-to-orbit conversion of angular momentum, which can be associated with the spin Hall effect, occurs upon scattering of polarized plane waves on various non-planar objects, such as lenses or small scatterers, or in inhomogeneous anisotropic media.

    “Finally, the spin-orbit interaction of light and spin-to-orbit conversion of the angular momentum (which can be associated with the spin Hall effect) occurs upon the scattering of polarized plane waves on various non-planar objects, such as lenses or small scatterers, or in inhomogeneous anisotropic media [67,145 -152].”

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.
