Traveling Solitons in Long-Range Oscillator Chains
George Miloshevich, Jean Pierre Nguenang, Thierry Dauxois +2
We investigate the existence and propagation of solitons in a long-range extension of the quartic Fermi-Pasta-Ulam (FPU) chain of anharmonic oscillators. The coupling in the linear…
Internal wave attractors examined using laboratory experiments and 3D numerical simulations
Christophe Brouzet, Ilias Sibgatullin, H Scolan +2
In the present paper, we combine numerical and experimental approaches to study the dynamics of stable and unstable internal wave attractors. The problem is considered in a classic…
Nonlinear internal wave penetration via parametric subharmonic instability
S. J. Ghaemsaidi, S. Joubaud, T. Dauxois +2
We present the results of a laboratory experimental study of an internal wave field generated by harmonic, spatially-periodic boundary forcing from above of a density stratificatio…
