Dynamical large deviations and long-range correlations for local weak wave turbulence
Brice Douet, Freddy Bouchet
Wave turbulence describes the statistical dynamics of dispersive waves with weakly nonlinear interactions. While the classical kinetic equation captures the mean evolution of the w…
Langevin dynamics, large deviations and instantons for the quasi-geostrophic model and two-dimensional Euler equations
Freddy Bouchet, Jason Laurie, Oleg Zaboronski
We investigate a class of simple models for Langevin dynamics of turbulent flows, including the one-layer quasi-geostrophic equation and the two-dimensional Euler equations. Starti…
Vortex-density fluctuations, energy spectra and vortical regions in superfluid turbulence
Andrew W. Baggaley, Jason Laurie, Carlo F. Barenghi
Measurements of the energy spectrum and of the vortex-density fluctuation spectrum in superfluid turbulence seem to contradict each other. Using a numerical model, we show that at…
Stability criteria of the Vlasov equation and quasi-stationary states of the HMF model
Y. Y. Yamaguchi, J. Barr'e, F. Bouchet +2
We perform a detailed study of the relaxation towards equilibrium in the Hamiltonian Mean-Field (HMF) model, a prototype for long-range interactions in -particle dynamics. In pa…
Classification of phase transitions and ensemble inequivalence, in systems with long range interactions
Freddy Bouchet, Julien Barre
Systems with long range interactions in general are not additive, which can lead to an inequivalence of the microcanonical and canonical ensembles. The microcanonical ensemble may…
Birth and long-time stabilization of out-of-equilibrium coherent structures
Julien Barre, Freddy Bouchet, Thierry Dauxois +1
We study an analytically tractable model with long-range interactions for which an out-of-equilibrium very long-lived coherent structure spontaneously appears. The dynamics of this…
