Can a quantum mixmaster universe undergo a spontaneous inflationary phase?
Herve Bergeron, Jaime de Cabo Martin, Jean-Pierre Gazeau +1
We study a semiclassical model of the mixmaster universe. We first derive the quantum model and then introduce its semiclassical approximation. We employ a general integral quantiz…
Ambiguous power spectrum from a quantum bounce
Jaime de Cabo Martin, Przemysław Małkiewicz, Patrick Peter
A quantum cosmological bouncing model may exhibit an ambiguity stemming from the nonclassical nature of the background evolution: two classically equivalent theories can produce tw…
Unitarily inequivalent quantum cosmological bouncing models
Jaime de Cabo Martin, Przemysław Małkiewicz, Patrick Peter
By quantising the background as well as the perturbations in a simple one fluid model, we show that there exists an ambiguity in the choice of relevant variables, potentially leadi…
