Topological mechanical metamaterials have enabled new ways to control stress and
deformation propagation. Exemplified by Maxwell lattices, they have been studied …

We show the existence of breathing edge modes in the Su-Schrieffer-Heeger model with
cubic (Kerr) on-site nonlinearity, bifurcating from stationary edge solitons with propagation …

We report on a nonlinear scattering effect that challenges the notion of topological protection

We propose a procedure to engineer solid-state lattice models with superlattices of
interaction-coupled Bose-Einstein condensates. We show that the dynamical equation for …

In this work, we revisit the classic model of diatomic chain with cubic nonlinearity and
