Gradient catastrophe and Peregrine soliton in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
We explore the generation of extreme wave events in mechanical metamaterials using the regularization of the gradient catastrophe theory developed by A. Tovbis and M. Bertola for t…

Optically-Controlled Nano-Transducers Based on Cleaved Superlattices for Monitoring Gigahertz Surface Acoustic Vibrations
Changxiu Li, Nikolay Chigarev, Théo Thréard +6
Surface acoustic waves (SAWs) convey energy at subwavelength depths along surfaces. Using interdigital transducers (IDTs) and opto-acousto-optic transducers (OAOTs), researchers ha…
