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…
