    • Coexistence of ordinary elasticity and superfluidity in a model of a defect-free supersolid 
      Josserand, Christophe; Pomeau, Yves; Rica, Sergio (2007)
      The mechanical behavior of a supersolid is studied in the framework of a fully explicit model derived from the Gross-Pitaevskii equation without assuming any defect or vacancy. A set of coupled nonlinear partial differential ...
    • Condensation of classical nonlinear waves 
      Connaughton, Colm; Josserand, Christophe; Picozzi, Antonio; Pomeau, Yves; Rica, Sergio (AMERICAN PHYSICAL SOC, 2005-12-31)
      We study the formation of a large-scale coherent structure (a condensate) in classical wave equations by considering the defocusing nonlinear Schrodinger equation as a representative model. We formulate a thermodynamic ...
    • Self-similar singularities in the kinetics of condensation 
      Josserand, Christophe; Pomeau, Yves; Rica, Sergio (SPRINGER/PLENUM PUBLISHERS, 2006-11)
      In this article, we review how a condensate builds-up infinite time, by a self-similar blow-up of the solution of three different models of kinetic equations. After the blow-up time, the growth of the coherent phase is ...
    • Weak turbulence for a vibrating plate: Can one hear a Kolmogorov spectrum? 
      Düring, Gustavo; Josserand, Christophe; Rica, Sergio (AMERICAN PHYSICAL SOC, 2006-07-14)
      We study the long-time evolution of waves of a thin elastic plate in the limit of small deformation so that modes of oscillations interact weakly. According to the theory of weak turbulence (successfully applied in the ...
