Abstract
We use the formalism of two-mode squeezed states and the theory of gau ge invariant cosmological perturbations to calculate two-point correla tion functions and the entropy of density perturbations. In particular we discuss modulation in the power spectrum of density perturbations. We also present a simple picture for entropy in terms of the quantum noise in the state. The relevance of the entropy of density perturbati ons for large-scale structures in the universe is examined.
