Quantum cosmological background superposition and perturbation predictions
Kratika Mazde, Lisa Mickel, Patrick Peter
Predictions from early universe cosmology typically concern primordial perturbations generated during epochs where effects arising from the quantum nature of gravity may be importa…
Non-Gaussianities as a Signature of Quantumness of Quantum Cosmology
Hervé Bergeron, Przemysław Małkiewicz, Patrick Peter
We show that the consistent application of the rules of quantum mechanics to cosmological systems inevitably results in the so-called multiverse states in which neither the backgro…
Quantum entanglement and non-Gaussianity in the primordial Universe
Herve Bergeron, Przemyslaw Malkiewicz, Patrick Peter
We propose a new method to investigate signatures of a quantum gravity phase in the primordial state of cosmological perturbations. We formulate and study a quantum model of a pert…
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…
