Physical Hilbert Spaces in Quantum Gravity
Przemyslaw Malkiewicz
We summarize our investigation of the extent to which the choice of internal clock influences the dynamics in quantum models of gravity. Firstly, at the classical level, we define…
Affine Coherent States in Quantum Cosmology
Przemyslaw Malkiewicz
A brief summary of the application of coherent states in the examination of quantum dynamics of cosmological models is given. We discuss quantization maps, phase space probability…
Vibronic framework for quantum mixmaster universe
Hervé Bergeron, Ewa Czuchry, Jean-Pierre Gazeau +1
Following our previous papers concerning the quantization of the vacuum Bianchi-IX model within or beyond the Born-Oppenheimer and adiabatic approximation, we develop a more elabor…
Nonadiabatic bounce and an inflationary phase in the quantum mixmaster universe
Herve Bergeron, Ewa Czuchry, Jean-Pierre Gazeau +1
Following our previous paper, Bergeron et al, Smooth quantum dynamics of the mixmaster universe, Phys. Rev. D 92, 061302(R) (2015), concerning the quantization of the vacuum Bianch…
What is Dynamics in Quantum Gravity?
Przemyslaw Malkiewicz
The appearance of Hamiltonian constraint in the canonical formalism for general relativity reflects the lack of a fixed external time. The dynamics of general relativistic systems…
Smooth Bounce in Affine Quantization of Bianchi I
Herve Bergeron, Andrea Dapor, Jean-Pierre Gazeau +1
We present the affine coherent state quantization of the Bianchi I model. As in our previous paper on quantum theory of Friedmann models, we employ a variable associated with a per…
