Author Correction: Elastic pseudospin transport for integratable topological phononic circuits
Abstract
The original version of this Article contained errors in the second sentence in the legend of Fig. 1, which incorrectly read `These two elastic insulators are identical in lattice constant a (3a0), plate thickness (0.4a0), and radius of perforated holes r (0.18a0) but different hole-center distance characterized by b.' The correct version states `plate thickness (√3 × 0.4a0)' in place of `plate thickness (0.4a0)' and `radius of perforated holes r (√3 × 0.18a0)' rather than `radius of perforated holes r (0.18a0)'.The first sentence of the `Sample preparation' section of the Methods originally incorrectly read `Our samples are prepared exclusively on polished stainless-steel plates (Type 201, mass density 7803 kg m-3) with a fixed plate thickness 7.82 mm.' In the corrected version, `mass density 7903 kg m-3' replaces `mass density 7803 kg m-3'.The second sentence in the legend of Supplementary Fig. 3, originally incorrectly read `The symmetry of the phononic crystal remains unchanged as C6ν, and thickness of the substrates H (equals to 0.4a0), lattice constant a (equals to 3a0) and radius of perforated holes r (equals to 0.18 a0) maintain constant.' The correct version states `√3 × 0.4a0' in place of `0.4a0' and `√3 × 0.18a0' rather than `0.18a0'.This has been corrected in both the PDF and HTML versions of the Article.
