Formation of mechanical rogue waves
Yasuhiro Miyazawa, Christopher Chong, Panayotis G. Kevrekidis +1
Rogue waves, characterized by their abrupt and extreme localization in space and time, have evolved from maritime folklore to subjects of intense study across diverse fields, from…
Unveiling Solitonic Collisions in Mechanical Metamaterials
Yasuhiro Miyazawa, Christopher Chong, Panayotis G. Kevrekidis +1
Interactions between solitary waves have been pivotal to understanding nonlinear phenomena across various disciplines. The dynamics of rarefaction solitary waves holds great potent…
Shock and Rarefaction Waves in Generalized Hertzian Contact Models
Hiromi Yasuda, Christopher Chong, Jinkyu Yang +1
In the present work motivated by generalized forms of the Hertzian dynamics associated with granular crystals, we consider the possibility of such models to give rise to both shock…
Exciting and Harvesting Vibrational States in Harmonically Driven Granular Chains
C. Chong, E. Kim, E. G. Charalampidis +6
This article explores the excitation of different vibrational states in a spatially extended dynamical system through theory and experiment. As a prototypical example, we consider…
Formation of rarefaction waves in origami-based metamaterials
Hiromi Yasuda, Christopher Chong, Efstathios G. Charalampidis +2
We investigate the nonlinear wave dynamics of origami-based metamaterials composed of Tachi-Miura polyhedron (TMP) unit cells. These cells exhibit strain softening behavior under c…
sine-Gordon Equation: From Discrete to Continuum
M. Chirilus-Bruckner, C. Chong, P. G. Kevrekidis +1
In the present Chapter, we consider two prototypical Klein-Gordon models: the integrable sine-Gordon equation and the non-integrable model. We focus, in particular, on two of…
Damped-Driven Granular Crystals: An Ideal Playground for Dark Breathers and Multibreathers
C. Chong, F. Li, J. Yang +4
By applying an out-of-phase actuation at the boundaries of a uniform chain of granular particles, we demonstrate experimentally that time-periodic and spatially localized structure…
Dark Breathers in Granular Crystals
C. Chong, P. G. Kevrekidis, G. Theocharis +1
We present a study of the existence, stability and bifurcation structure of families of dark breathers in a one-dimensional uniform chain of spherical beads under static load. A de…
Multistable Solitons in Higher-Dimensional Cubic-Quintic Nonlinear Schroedinger Lattices
C. Chong, R. Carretero-Gonzalez, B. A. Malomed +1
We study the existence, stability, and mobility of fundamental discrete solitons in two- and three-dimensional nonlinear Schroedinger lattices with a combination of cubic self-focu…
