Abstract

We discover a pair of stable three-dimensional (3D) Dirac points, a 3D photonic analog of graphene, in all-dielectric photonic crystals using structures commensurate with nanofabrication for visible-frequency photonic applications. The Dirac points carry nontrivial ${Z}_{2}$ topology and emerge for a large range of material parameters in hollow cylinder hexagonal photonic crystals. From Kramers theorem and group theory, we find that only the ${C}_{6}$ symmetry leads to point group symmetry stabilized Dirac points in 3D all-dielectric photonic crystals. The Dirac points are characterized using $\stackrel{P\vec}{k}\ifmmode\cdot\else\textperiodcentered\fi{}\stackrel{P\vec}{P}$ theory for photonic bands in combination with symmetry analysis. Breaking inversion symmetry splits the Dirac points into Weyl points. The physical properties and experimental consequences of Dirac points are also studied. The Dirac points are found to be robust against parameter tuning and weak disorders.

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

  • Weak disorders that preserve the crystalline symmetry on average should preserve the Dirac points and their topological surface states.

    “Weak disorders that preserve the crystalline symmetry on average should preserve the DPs and their topological surface states.29,47”

    From Type-II Dirac photons (2017) · cites this paper as [29]

    Appendix H (p. 10) says that weak fabrication errors can preserve the Dirac points. Appendix E (pp. 8–10) describes topological boundary states in an inversion-symmetry-broken structure, but does not establish that weak disorder preserves those states. The paper also does not address the claim's specific condition that crystalline symmetry be preserved on average. (LLM, conf=0.88)

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.
