Opening and closing a bandgap via alternating softening and hardening nonlinearities
Weijian Jiao
Recent studies have shown some unusual nonlinear dispersion behaviors that are disconnected from the linear regime. However, existing analytical techniques, such as perturbation me…
Nucleation of transition waves via collisions of elastic vector solitons
Hiromi Yasuda, Hang Shu, Weijian Jiao +2
In this work, we show that collisions of one type of nonlinear wave can lead to generation of a different kind of nonlinear wave. Specifically, we demonstrate the formation of topo…
Phase transitions in 2D multistable mechanical metamaterials via collisions of soliton-like pulses
Weijian Jiao, Hang Shu, Vincent Tournat +2
In this work, we report observations of phase transitions in 2D multistable mechanical metamaterials that are initiated by collisions of soliton-like pulses in the metamaterial. An…
Tunable bandgaps and symmetry breaking in magneto-mechanical metastructures inspired by multi-layer 2D materials
Kuan Zhang, Weijian Jiao, Stefano Gonella
In this Letter, we introduce a paradigm to realize magneto-mechanical metastructures inspired by multi-layer 2D materials, such as graphene bilayers. The metastructures are intende…
Wavenumber-space band clipping in nonlinear periodic structures
Weijian Jiao, Stefano Gonella
In weakly nonlinear systems, the main effect of cubic nonlinearity on wave propagation is an amplitude-dependent correction of the dispersion relation. This phenomenon can manifest…
Nonlinear harmonic generation in two-dimensional lattices of repulsive magnets
Weijian Jiao, Stefano Gonella
In this Letter, we provide experimental evidence of nonlinear wave propagation in a triangular lattice of repulsive magnets supported by an elastic foundation of thin pillars and w…
Dynamics of interacting particle systems: Modeling implications of the repulsive interactions and experiments on magnetic prototypes
Weijian Jiao, Stefano Gonella
In this work, we investigate the dynamics of interacting particle systems subjected to repulsive forces, such as lattices of magnetized particles. To this end, we first develop a g…
Doubly-nonlinear waveguides with self-switching functionality selection capabilities
Weijian Jiao, Stefano Gonella
In this article, we investigate the effects of the interplay between quadratic and cubic nonlinearities on the propagation of elastic waves in periodic waveguides. Through this fra…
