  We study the dynamics of Bogoliubov excitations of a Bose-Einstein condensate
in the quasiperiodic kicked rotor. In the weakly interacting regime, the
condensate is stable and both the condensate and the excitations undergo a
phase transition from a quasilocalized to a diffusive regime. The corresponding
critical exponents are identical for the condensate and the excitations, and
compare very well with the value $\nu\approx1.6$ for non-interacting particles.
