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…
Energy spreading, equipartition and chaos in lattices with non-central forces
Arnold Ngapasare, Geogios Theocharis, Olivier Richoux +2
We numerically study a one dimensional, nonlinear lattice model which in the linear limit is relevant to the study of bending (flexural) waves. In contrast with the classic one dim…
Disorder-induced topological phase transition in a 1D mechanical system
Xiaotian Shi, Ioannis Kiorpelidis, Rajesh Chaunsali +3
We numerically investigate the topological phase transition induced purely by disorder in a spring-mass chain. We employ two types of disorders - chiral and random types - to explo…
Acoustic Su-Schrieffer-Heeger lattice: Direct mapping of acoustic waveguides to Su-Schrieffer-Heeger model
Antonin Coutant, Audrey Sivadon, Liyang Zheng +4
Topological physics strongly relies on prototypical lattice model with particular symmetries. We report here on a theoretical and experimental work on acoustic waveguides that is d…
