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…
Discrete resonant Rossby/drift wave triads: an explicit parameterisation and a fast direct numerical search algorithm
Umar Hayat, Shahid Amanullah, Shane Walsh +1
We report results on the explicit parameterisation of discrete Rossby-wave resonant triads of the Charney-Hasegawa-Mima equation in the small-scale limit (i.e. large Rossby deforma…
