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…
Self-organization of ultrasound in viscous fluids
V. J. Sanchez-Morcillo, J. Martinez-Mora, I. Perez-Arjona +2
We report the theoretical and experimental demonstration of pattern formation in acoustics. The system is an acoustic resonator containing a viscous fluid. When the system is drive…
Diffusion stabilizes cavity solitons in bidirectional lasers
Isabel Perez-Arjona, Victor Sanchez-Morcillo, Javier Redondo +2
We study the influence of field diffusion on the spatial localized structures (cavity solitons) recently predicted in bidirectional lasers. We find twofold positive role of the dif…
Derivation of the spatio-temporal model equations for the thermoacoustic resonator
Isabel Perez-Arjona, Victor J. Sanchez-Morcillo, German de Valcarcel
We derive the model equations describing the thermoacoustic resonator, that is, an acoustical resonator containing a viscous medium inside. Previous studies on this system have add…
