Classical and quantum aspects of perturbations in Primordial Universe
Alice Boldrin
In this work, our aim is to obtain a Hamiltonian formulation suitable for canonical quantization. Moreover, we assume that the early Universe can be described with fewer initial sy…

Time problem in primordial perturbations
Alice Boldrin, Przemysław Małkiewicz, Patrick Peter
We study the non-unitary relation between quantum gravitational models defined using different internal times. We show that despite the non-unitarity, it is possible to provide a p…

The Gauge issue and the Hamiltonian theory of cosmological perturbations
Alice Boldrin
We present a general formalism for the Hamiltonian description of perturbation theory around any spatially homogeneous spacetime. We employ and refine the Dirac method for constrai…
