Abstract

Skyrmions with topologically stable configuration have shown a promising route toward high-density magnetic and photonic information processing due to their defect-immune and low-driven energy. Here, we experimentally report and observe the existence of phononic skyrmions as new topological structures formed by the three-dimensional hybrid spin of elastic waves. We demonstrate that the frequency-independent spin configuration leads to ultra-broadband feature of phononic skyrmions, which can be produced in any solid structure, including chip-scale ones. We further experimentally show the excellent robustness of the flexibly movable phononic skyrmion lattices against local defects of disorder, sharp corners, and even rectangular holes. Our research opens a vibrant horizon toward an unprecedented way for elastic wave manipulation and structuration by spin configuration and offers a promising lever for alternative phononic technologies, including information processing, biomedical testing, and wave engineering.

  • Optical skyrmions can interact with magnetic skyrmions, allowing a route to manipulate these magnetic particles.

    “Optical skyrmions can interact with magnetic skyrmions allowing for a route to manipulate these magnetic particles [103][104][105].”

    From Optical skyrmions and other topological quasiparticles of light (2024) · cites this paper as [104]

    The Introduction mentions magnetic skyrmions and the extension of skyrmions to photonics, but does not describe an interaction between them. The Discussion addresses coupling between elastic and electromagnetic waves, not using optical skyrmions to manipulate magnetic skyrmions. Searches for optical–magnetic interaction and manipulation found no supporting passage in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured

  • Skyrmions can be driven by the skyrmion Hall effect, spin-orbit torque, and light.

    “and can be driven by the skyrmion Hall effect [61,62], spin-orbit torque [99,100], and even the light [101][102][103][104][105].”

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.
