| Resumen en inglés | We propose a wave kinetic description of superfluidity in Bose Einstein condensates. This is based on the traditional two-fluid model, where in contrast with current analysis, the two fluids are treated on similar grounds. Each of the fluids (the condensed gas and the phonon gas) is described by a similar wave kinetic equation. These two equations are coupled. Perturbations of the coupled fluids lead to the formation of excitons which, in the appropriate limits, tend to the first and second sound waves |
