Description
In order to shed light on the quantum to classical transition of the
primordial perturbations during inflation, we investigated
the decoherence of a system of scalar curvature perturbations
induced by an unobservable environment of deep subhorizon tensorial
modes. We computed the associated corrections to the cosmological correlation
functions, looking for distinguishable signatures which could, in
future observations, prove the quantum origin of primordial perturbations.
In doing this, we commented on proposed techniques to deal with non-
Markovianity (i.e. memory effects in the environment, which drastically
complicates calculations), which seems to be ubiquitous in an inflationary
framework.
