Amortissement des phonons dans un superfluide 2D : insuffisance de la règle d’or de Fermi à basse température

It is generally accepted that the phonon gas of a superfluid always enters a weak coupling regime at sufficiently low temperatures, whatever the strength of the interactions between the underlying particles (constitutive of the superfluid). Thus, in this limit, we should always be able to calculate...
