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…
Polydispersed Granular Chains: From Long-lived Chaotic Anderson-like Localization to Energy Equipartition
V. Achilleos, G. Theocharis, Ch. Skokos
We investigate the dynamics of highly polydispersed finite granular chains. From the spatio-spectral properties of small vibrations, we identify which particular single-particle di…
Bright and Gap Solitons in Membrane-Type Acoustic Metamaterials
Jiangyi Zhang, Vicente Romero-García, Georgios Theocharis +3
We study analytically and numerically envelope solitons (bright and gap solitons) in a one-dimensional, nonlinear acoustic metamaterial, composed of an air-filled waveguide periodi…
