Inhomogeneities from quantum collapse scheme without inflation
  In this work, we consider the problem of the emergence of seeds of cosmic
structure in the framework of the non-inflationary model proposed by Hollands
and Wald. In particular, we consider a modification to that proposal designed
to account for breaking the symmetries of the initial quantum state, leading to
the generation of the primordial inhomogeneities. This new ingredient is
described in terms of a spontaneous reduction of the wave function. We
investigate under which conditions one can recover an essentially scale free
spectrum of primordial inhomogeneities, and which are the dominant deviations
that arise in the model as a consequence of the introduction of the collapse of
the quantum state into that scenario.
