Branche d’excitation collective du continuum dans les gaz de fermions condensés par paires : étude analytique et lois d’échelle
The pair-condensed unpolarized spin-$1/2$ Fermi gases have a collective excitation branch in their pair-breaking continuum (V.A. Andrianov, V.N. Popov, 1976). We study it at zero temperature, with the eigenenergy equation deduced from the linearized time-dependent BCS theory and extended analyticall...
