Query: Collective dynamics of Fermi-Bose mixtures with an oscillating
  scattering length   Collective oscillations of superfluid mixtures of ultra cold fermionic and
bosonic atoms are investigated while varying the fermion-boson scattering
length. We study the dynamics with respect to excited center of mass modes and
breathing modes in the mixture. Parametric resonances are also analyzed when
the scattering length varies periodically in time, by comparing partial
differential equation (PDE) models and ordinary differential equation (ODE)
models for the dynamics. An application to the recent experiment with fermionic
$^{6}$Li and bosonic $^{7}$Li atoms, which approximately have the same masses,
is discussed.
