Dynamics of primordial fields in quantum cosmological spacetimes
Przemysław Małkiewicz, Artur Miroszewski
Quantum cosmological models are commonly described by means of semiclassical approximations in which a smooth evolution of the expectation values of elementary geometry operators r…
Quantum dynamics in Weyl-Heisenberg coherent states
Artur Miroszewski
The article explores a new formalism for describing motion in quantum mechanics. The construction is based on generalized coherent states with evolving fiducial vector. Weyl-Heisen…
Quantum phase space trajectories with application to quantum cosmology
Przemysław Małkiewicz, Artur Miroszewski, Hervé Bergeron
We develop an approach to quantum dynamics based on quantum phase space trajectories. The latter are built from a unitary irreducible representation of the symmetry group of the re…
Internal clock formulation of quantum mechanics
Przemysław Małkiewicz, Artur Miroszewski
The basic tenet of the present work is the assumption of the lack of external and fixed time in the Universe. This assumption is best embodied by general relativity, which replaces…
