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…

Stochastic Resonance in the Fermi-Pasta-Ulam Chain
George Miloshevich, Ramaz Khomeriki, Stefano Ruffo
We consider a damped -Fermi-Pasta-Ulam chain, driven at one boundary subjected to stochastic noise. It is shown that, for a fixed driving amplitude and frequency, increasing the…
