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…
Approximate rogue wave solutions of the forced and damped Nonlinear Schrödinger equation for water waves
Miguel Onorato, Davide Proment
We consider the effect of the wind and the dissipation on the nonlinear stages of the modulational instability. By applying a suitable transformation, we map the forced/damped Nonl…
Nonequilibrium steady solutions of the Boltzmann equation
Davide Proment, Miguel Onorato, Pietro Asinari +1
We report a study of the homogeneous isotropic Boltzmann equation for an open system. We seek for nonequilibrium steady solutions in presence of forcing and dissipation. Using the…
Sustained turbulence in the three-dimensional Gross-Pitaevskii model
Davide Proment, Sergey Nazarenko, Miguel Onorato
We study the 3D forced-dissipated Gross-Pitaevskii equation. We force at relatively low wave numbers, expecting to observe a direct energy cascade and a consequent power-law spectr…
Energy cascades and spectra in turbulent Bose-Einstein condensates
Davide Proment, Sergey Nazarenko, Miguel Onorato
We present a numerical study of turbulence in Bose-Einstein condensates within the 3D Gross-Pitaevskii equation. We concentrate on the direct energy cascade in forced-dissipated sy…
