Enlightening the CSL model landscape in inflation
  We propose a novel realization for the natural extrapolation of the
continuous spontaneous localization (CSL) model, in order to account for the
origin of primordial inhomogeneities during inflation. This particular model is
based on three main elements: (i) the semiclassical gravity framework, (ii) a
collapse-generating operator associated to a relativistic invariant scalar of
the energy-momentum tensor, and (iii) an extension of the CSL parameter(s) as a
function of the spacetime curvature. Furthermore, employing standard
cosmological perturbation theory at linear order, and for a reasonable range
within the parameter space of the model, we obtain a nearly scale invariant
power spectrum consistent with recent observational CMB data. This opens a vast
landscape of different options for the application of the CSL model to the
cosmological context, and possibly sheds light on searches for a full covariant
version of the CSL theory.
