Single -flux hosting topological defect modes in bilayer acoustic metamaterials
Renaud Cote, Marc Pachebat, Antonin Coutant
The bulk-boundary correspondence, which relates topological properties of a material in the bulk to the presence of robust modes localized on the edge, is at the core of the now ma…
Canonical scattering problem in topological metamaterials: Valley-Hall modes through a bend
Theo Torres, Cédric Bellis, Régis Cottereau +1
We study the amount of backscattering of Valley Hall modes in a classical topological insulator. In reciprocal systems, the conservation of the valley index has been argued to be a…
Latent Su-Schrieffer-Heeger models
Malte Röntgen, Xuelong Chen, Wenlong Gao +5
The Su-Schrieffer-Heeger (SSH) chain is the reference model of a one-dimensional topological insulator. Its topological nature can be explained by the quantization of the Zak phase…
Surface impedance and topologically protected interface modes in one-dimensional phononic crystals
Antonin Coutant, Bruno Lombard
When semi-infinite phononic crystals (PCs) are in contact, localized modes may exist at their boundary. The central question is generally to predict their existence and to determin…
Topologically invisible defects in chiral mirror lattices
Antonin Coutant, Li-Yang Zheng, Vassos Achilleos +3
One of the hallmark of topological insulators is having conductivity properties that are unaffected by the possible presence of defects. In this work, we go beyond backscattering i…
Subwavelength Su-Schrieffer-Heeger topological modes in acoustic waveguides
Antonin Coutant, Vassos Achilleos, Olivier Richoux +2
Topological systems furnish a powerful way of localizing wave energy at edges of a structured material. Usually this relies on Bragg scattering to obtain bandgaps with nontrivial t…
