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…
Dynamics of interacting dark soliton stripes
P. G. Kevrekidis, Wenlong Wang, G. Theocharis +3
In the present work we examine the statics and dynamics of multiple parallel dark soliton stripes in a two-dimensional Bose-Einstein condensate. Our principal goal is to study the…
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…
Highly Nonlinear Wave Propagation in Elastic Woodpile Periodic Structures
E. Kim, F. Li, C. Chong +3
In the present work, we experimentally implement, numerically compute with and theoretically analyze a configuration in the form of a single column woodpile periodic structure. Our…
Locally Resonant Granular Chain
Luca Bonanomi, Georgios Theocharis, Chiara Daraio
We report the design and testing of a tunable and nonlinear mechanical metamaterial, called locally resonant granular chain. It consists of a one-dimensional array of hollow spheri…
