Cosmological dynamics in spin-foam loop quantum cosmology: challenges and prospects
David A. Craig, Parampreet Singh
We explore the structure of the spin foam-like vertex expansion in loop quantum cosmology and discuss properties of the corresponding amplitudes, with the aim of elucidating some o…
The consistent histories approach to loop quantum cosmology
David A. Craig
We review the application of the consistent (or decoherent) histories formulation of quantum theory to canonical loop quantum cosmology. Conventional quantum theory relies cruciall…
Consistent probabilities in loop quantum cosmology
David A. Craig, Parampreet Singh
A fundamental issue for any quantum cosmological theory is to specify how probabilities can be assigned to various quantum events or sequences of events such as the occurrence of s…
Dynamical eigenfunctions and critical density in loop quantum cosmology
David A. Craig
We offer a new, physically transparent argument for the existence of the critical, universal maximum matter density in loop quantum cosmology for the case of a flat Friedmann-Lemai…
Consistent Probabilities in Wheeler-DeWitt Quantum Cosmology
David A. Craig, Parampreet Singh
We give an explicit, rigorous framework for calculating quantum probabilities in a model theory of quantum gravity. Specifically, we construct the decoherence functional for the Wh…
Consistent Histories in Quantum Cosmology
David A. Craig, Parampreet Singh
We illustrate the crucial role played by decoherence (consistency of quantum histories) in extracting consistent quantum probabilities for alternative histories in quantum cosmolog…
