Granular Graphene: direct observation of zigzag and armchair edge waves
Li-Yang Zheng, Florian Allein, Vincent Tournat +2
We propose a mechanical granular graphene obtained by replacing the carbon atoms with macroscopic spherical stainless steel beads in contact. The experimental measured dispersion r…
Chaos and Anderson Localisation in Disordered Classical Chains: Hertzian vs FPUT models
A. Ngapasare, G. Theocharis, O. Richoux +2
We numerically investigate the dynamics of an one-dimensional disordered lattice using the Hertzian model, describing a granular chain, and the Fermi-Pasta-Ulam-Tsingou model…
Duality of bounded and scattering wave systems with local symmetries
I. Kiorpelidis, F. K. Diakonos, G. Theocharis +4
We investigate the spectral properties of a class of hard-wall bounded systems, described by potentials exhibiting domain-wise different local symmetries. Tuning the distance of th…
Subwavelength Interferometric Control of Absorption in Three-port Acoustic Network
O. Richoux, V. Achilleos, G. Theocharis +1
Utilizing the effect of losses, we show that symmetric 3-port devices exhibit coherent perfect absorption of waves and we provide the corresponding conditions on the reflection and…
