Wave-packet spreading in the disordered and nonlinear Su-Schrieffer-Heeger chain
Bertin Many Manda, Vassos Achilleos, Olivier Richoux +2
We numerically investigate the characteristics of the long-time dynamics of a single-site wave-packet excitation in a disordered and nonlinear Su-Schrieffer-Heeger model. In the li…
Finite size effects on topological interface states in one-dimensional scattering systems
P. A. Kalozoumis, G. Theocharis, V. Achilleos +3
One-dimensional topological edge modes are usually studied considering the interface between two different semi infinite periodic crystals (PCs) with inverted band structure around…
Transparency robust to disorder in a periodic array of Helmholtz resonators
Olivier Richoux, Agnès Maurel, Vincent Pagneux
In this paper, the influence of disorder on 1D periodic lattice of resonant scatterers is inspected. These later have multiple resonance frequencies which produce bandgap in the tr…
