Summary
The nature of nonlinear third-sound waves and the concomitant nonlinear dispersion of a thin superfluid film, subject to the van der Waals interaction due to a substrate, are investigated.
Riassunto
Si studiano la natura delle onde non lineari del terzo suono e la concomitante dispersione di un film sottile superfluido, soggetto all'interazione di Van der Waals dovuta al substrato.
Резюме
