Journal ArticleDOI
Curvature invariants, geodesics, and the strength of singularities in Bianchi-I loop quantum cosmology
TL;DR: In this paper, the effects of the underlying quantum geometry in loop quantum cosmology on spacetime curvature invariants and the extendibility of geodesics in the Bianchi-I model for matter with a vanishing anisotropic stress were investigated.
Journal ArticleDOI
Exotic singularities and spatially curved Loop Quantum Cosmology
TL;DR: In this paper, the authors investigate the occurrence of various exotic spacelike singularities in the past and the future evolution of k = ± 1 Friedmann-Robertson-Walker model and loop quantum cosmology using a sufficiently general phenomenological model for the equation of state.
Journal ArticleDOI
Loop Quantum Gravity and the Cyclic Universe
TL;DR: In this article, the authors investigate the effects of loop quantum gravity on the cyclic universe potential, and find that loop quantum effects can dramatically alter the near-collision dynamics of cyclic scenarios, such that the scalar field is effectively frozen by loop quantum friction.
Journal ArticleDOI
Contrasting features of anisotropic loop quantum cosmologies: The role of spatial curvature
Brajesh Gupt,Parampreet Singh +1 more
TL;DR: In this paper, the authors investigated the properties of the energy density and the expansion and shear scalars in Bianchi-II and BianchiIX spacetimes, which have been recently loop quantized using the connection operator approach.
Journal ArticleDOI
From black holes to white holes: a quantum gravitational, symmetric bounce
TL;DR: In this paper, the authors show that quantization ambiguities can mitigate or even qualitatively change some key features of physics of singularity resolution, which are potentially helpful in motivating and constructing symmetric black to white hole transition scenarios.
