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…

Envelope vector solitons in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
In this paper, we employ a combination of analytical and numerical techniques to investigate the dynamics of lattice envelope vector soliton solutions propagating within a one-dime…
