Strain topological metamaterials
Florian Allein, Adamantios Anastasiadis, Rajesh Chaunsali +4
Topological physics has revolutionised materials science, introducing topological insulators and superconductors with applications from smart materials to quantum computing. Bulk-b…
Duality of Topological Edge States in a Mechanical Kitaev Chain
Florian Allein, Rajesh Chaunsali, Adamantios Anastasiadis +4
We theoretically investigate and experimentally demonstrate the existence of topological edge states in a mechanical analog of the Kitaev chain with a non-zero chemical potential.…
Spectral flow of a localized mode in elastic media
Marco Miniaci, Florian Allein, Raj Kumar Pal
The introduction of structural defects in otherwise periodic media is well known to grant exceptional space control and localization of waves in various physical fields, including…
Growing Phenotype-controlled Phononic Materials from Plant Cells Scaffolds
Maroun Abi Ghanem, Liliane Khoryati, Reza Behrou +5
Biological composites offer self-healing properties, biocompatibility, high responsivity to external stimuli, and multifunctionality, due, in part, to their complex, hierarchical m…
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…
Transversal-rotational and zero group velocity modes in tunable magneto-granular phononic crystals
F. Allein, V. Tournat, V. E. Gusev +1
We report on the design and operation of a 1D magneto-granular phononic crystal composed of a chain of steel spherical beads on top of permanent magnets. The magnetic field of the…
Tunable magneto-granular phononic crystals
F. Allein, V. Tournat, V. E. Gusev +1
This paper reports on the study of the dynamics of 1D magneto-granular phononic crystals composed of a chain of spherical steel beads inside a properly designed magnetic field. Thi…
