Anomalous correlators, "ghost" waves and nonlinear standing waves in the -FPUT system
Joseph Zaleski, Miguel Onorato, Yuri V Lvov
We show that Hamiltonian nonlinear dispersive wave systems with cubic nonlinearity and random initial data develop, during their evolution, anomalous correlators. These are respons…
Universal route to thermalization in weakly-nonlinear one-dimensional chains
Lorenzo Pistone, Sergio Chibbaro, Miguel Bustamante +2
We apply Wave Turbulence theory to describe the dynamics on nonlinear one-dimensional chains. We consider and Fermi-Pasta-Ulam-Tsingou (FPUT) systems, and the discrete nonl…
Exact discrete resonances in the Fermi-Pasta-Ulam-Tsingou system
Miguel D. Bustamante, Kevin Hutchinson, Yuri V. Lvov +1
In systems of N coupled anharmonic oscillators, exact resonant interactions play an important role in the energy exchange between normal modes. In the weakly nonlinear regime, thos…
Double scaling in the relaxation time in the -FPUT model
Yuri V Lvov, Miguel Onorato
We consider the original -Fermi-Pasta-Ulam-Tsingou (-FPUT) system; numerical simulations and theoretical arguments suggest that, for a finite number of masses, a statistical…
Origin of heavy tail statistics in equations of the Nonlinear Schrödinger type: an exact result
M. Onorato, D. Proment, G. El +2
We study the formation of extreme events in incoherent systems described by envelope equations, such as the Nonliner Schrödinger equation. We derive an identity that relates the ev…
A route to thermalization in the -Fermi-Pasta-Ulam system
Miguel Onorato, Lara Vozella, Davide Proment +1
We study the original -Fermi-Pasta-Ulam (FPU) system with and masses connected by a nonlinear quadratic spring. Our approach is based on resonant wave-wave intera…
