Mimicking alternatives to inflation with interacting spectator fields
  It has been argued that oscillatory features from spectator fields in the
primordial power spectrum could be a probe of alternatives to inflation. In
this work, we soften this claim by showing that the frequency and amplitude
dependence of the patterns appearing in these scenarios could be mimicked by
field interactions during inflation. The degeneracy of the frequency holds for
the $n$-point correlation functions, while the degeneracy of the amplitude is
broken at the level of non-gaussianities.
