Nonlinear dispersive waves in repulsive lattices
A. Mehrem, N. Jiménez, L. Salmerón-Contreras +4
The propagation of nonlinear waves in a lattice of repelling particles is studied theoretically and experimentally. A simple experimental setup is proposed, consisting in an array…
Energy localization and shape transformations in semiflexible polymer rings
Yuri B. Gaididei, Juan F. R. Archilla, Víctor J. Sánchez-Morcillo +1
Shape transformations in driven and damped molecular chains are considered. Closed chains of weakly coupled molecular subunits under the action of spatially homogeneous time-period…
Macroscopic acousto-mechanical analogy of a microbubble
Jennifer Chaline, Noé Jiménez, Ahmed Mehrem +3
Microbubbles, either in the form of free gas bubbles surrounded by a fluid or encapsulated bubbles used currently as contrast agents for medical echography, exhibit complex dynamic…
Ultradiscrete kinks with supersonic speed in a layered crystal with realistic potentials
Juan F. R. Archilla, Yuriy A. Kosevich, Noé Jiménez +2
We develop a dynamical model of the propagating nonlinear localized excitations, supersonic kinks, in the cation layer in a silicate mica crystal. We start from purely electrostati…
Enhancement of sound in chirped sonic crystals
V. Romero-García, R. Picó, A. Cebrecos +2
We propose and experimentally demonstrate a novel mechanism of sound wave concentration based on soft reflections in chirped sonic crystals. The reported controlled field enhanceme…
Formation of collimated sound beams by three-dimensional sonic crystals
A. Cebrecos, V. Romero-Garcia, R. Pico +4
A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An effic…
