Journal ArticleDOI
Quantum Nature of the Big Bang: Improved dynamics
TL;DR: In this article, an improved Hamiltonian constraint operator is introduced in loop quantum cosmology for the isotropic model with a massless scalar field and the big bang is replaced by a quantum bounce.
Journal ArticleDOI
Quantum Nature of the Big Bang
TL;DR: The known results on the resolution of the big-bang singularity in loop quantum cosmology are significantly extended, and unlike in other approaches the quantum evolution is deterministic across the deep Planck regime.
Journal ArticleDOI
Quantum nature of the big bang: An analytical and numerical investigation
TL;DR: In this article, the authors developed analytical and numerical methods to analyze the quantum nature of the big bang in the setting of loop quantum cosmology and provided a conceptual framework and technical tools which can be used in more general models.
Journal ArticleDOI
Loop quantum cosmology of k = 1 FRW models
Abhay Ashtekar,Abhay Ashtekar,Tomasz Pawlowski,Parampreet Singh,Kevin Vandersloot,Kevin Vandersloot +5 more
TL;DR: In this article, the closed, $k=1, FRW model coupled with a massless scalar field is investigated in the framework of loop quantum cosmology using analytical and numerical methods.
Journal ArticleDOI
Time and a physical Hamiltonian for quantum gravity.
TL;DR: A nonperturbative quantization of general relativity coupled to dust, leading to a physical Hamiltonian with spatial diffeomorphism symmetry that provides a complete theory of quantum gravity and puts applications to cosmology, quantum gravitational collapse, and Hawking radiation within technical reach.
