On the Physical Hilbert Space of Loop Quantum Cosmology
, 2004 In this paper we present a model of Riemannian loop quantum cosmology with a self-adjoint quantum scalar constraint. The physical Hilbert space is constructed using refined algebraic quantization.

Prediction in Quantum Cosmology [PDF]
, 1987 Lectures by the author at the 1986 Cargese summer school modestly corrected and uploaded for greater accessibility. Some of the author's views on the quantum mechanics of cosmology have changed from those presented here but may still be of historical interest.

, 2020 Principles of a cosmological model based on the electromagnetic quantum vacuum. Space is infinite and eternal composed of the quantum vacuum field, which is at the origin of finite “universe” of ordinary matter or antimatter, generated from the quantum vacuum and vanishing back to the vacuum state following a process of creation-annihilation mechanism.

Reports in Advances of Physical SciencesThis paper aims to demonstrate that modern cosmology has overlooked the systematic and holistic aspects of the universe’s evolution. It is based on the notion that the primordial universe comprised a two-component quantum superfluid and a synthesis of ...

New ekpyrotic quantum cosmology
Physics Letters B, 2015 Ekpyrotic instantons describe the emergence of classical contracting universes out of the no-boundary quantum state. However, up to now these instantons ended in a big crunch singularity.

LETTER: A Simple Quantum Cosmology [PDF]
General Relativity and Gravitation, 2001 A simple and surprisingly realistic model of the origin of the universe can be developed using the Friedmann equation from general relativity, elementary quantum mechanics, and the experimental values of h, c, G and the proton mass. The model assumes there are N space dimensions (with N > 6) and the potential constraining the radius r of the ...

QUANTUM COSMOLOGY WITH ROTATION
International Journal of Modern Physics A, 2005 The rotation of astronomical objects may be of a cosmological origin due to the Universe's specific angular momentum estimates proving to exceed those for spiral galaxies. The problem is expected to be solved in the framework of quantum geometrodynamics.
