Induced interaction and crystallization of self-localized impurity fields in a Bose-Einstein condensate
Sergio Rica, David C. Roberts
We model the behavior of N classical impurity fields immersed in a larger Bose-Einstein condensate by N+1 coupled nonlinear Schrodinger equations in 1, 2, and 3 space dimensions. W…
Impurity crystal in a Bose-Einstein condensate
David C. Roberts, Sergio Rica
We investigate the behavior of impurity fields immersed in a larger condensate field in 1, 2, and 3 dimensions. We discuss the localization of a single impurity field within a cond…
Coexisting ordinary elasticity and superfluidity in a model of defect-free supersolid
Christophe Josserand, Yves Pomeau, Sergio Rica
We present the mechanics of a model of supersolid in the frame of the Gross-Pitaevskii equation at that do not require defects nor vacancies. A set of coupled nonlinear part…
Can we hear Kolmogorov spectra?
Gustavo During, Christophe Josserand, Sergio Rica
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 t…
Condensation of classical nonlinear waves
Colm Connaughton, Christophe Josserand, Antonio Picozzi +2
We study the formation of a large-scale coherent structure (a condensate) in classical wave equations by considering the defocusing nonlinear Schrödinger equation as a representati…
