Two Fluid Quantum Bouncing Cosmology I: Theoretical Model
Sandro D. P. Vitenti, Nelson Pinto-Neto, Patrick Peter +1
Bouncing cosmologies offer an alternative to inflation by resolving the initial singularity through a contracting phase followed by a bounce into expansion. In many such models, th…

Non-Gaussianities as a Signature of Quantumness of Quantum Cosmology
Hervé Bergeron, PrzemysÅaw MaÅkiewicz, 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…
