Ring-Shaped Linear Waves and Solitons in a Square Lattice of Acoustic Waveguides
I. Ioannou Sougleridis, O. Richoux, V. Achilleos G. Theocharis +1
We study the propagation of both low- and high-amplitude ring-shaped sound waves in a 2D square lattice of acoustic waveguides with Helmholtz resonators. We show that the inclusion…

Existence and characterization of edge states in an acoustic trimer Su-Schrieffer-Heeger model
I. Ioannou Sougleridis, A. Anastasiadis, O. Richoux +4
We report on a direct mapping of acoustic slender waveguides to the one dimensional trimer Su- Schrieffer-Heeger model, with neither chiral nor mirror symmetry. Importantly, we can…
