Observation of mechanical kink control and generation via phonons
Kai Qian, Nan Cheng, Francesco Serafin +4
Kinks (or domain walls) are localized transitions between distinct ground states associated with a topological invariant, and are central to many phenomena across physics, from con…
Transverse instability and dynamics of nonlocal bright solitons
G. N. Koutsokostas, G. Theocharis, T. P. Horikis +2
We study the transverse instability and dynamics of bright soliton stripes in two-dimensional nonlocal nonlinear media. Using a multiscale perturbation method, we derive analytical…
Wave Propagation in a Strongly Nonlinear Locally Resonant Granular Crystal
K. Vorotnikov, Y. Starosvetsky, G. Theocharis +1
In this work, we study the wave propagation in a recently proposed acoustic structure, the locally resonant granular crystal. This structure is composed of a one-dimensional granul…
Hysteresis Loops and Multi-stability: From Periodic Orbits to Chaotic Dynamics (and Back) in Diatomic Granular Crystals
C. Hoogeboom, Y. Man, N. Boechler +4
In the present work we consider a diatomic granular crystal, consisting of alternating aluminum and steel spheres, where the first sphere is an aluminum one. The combination of dis…
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…
Discrete breathers at the interface between a diatomic and monoatomic granular chain
C. Hoogeboom, G. Theocharis, P. G. Kevrekidis
In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoa…
