Journal ArticleDOI
Quantum gravitational Kasner transitions in Bianchi-I spacetime
Brajesh Gupt,Parampreet Singh +1 more
TL;DR: In this paper, the authors investigated the geometrical structures of the Bianchi-I model in loop quantum cosmology, and found that geometric structures such as a cigar or a pancake form are possible in the pre-and post-bounce phases in physical evolution.
Journal ArticleDOI
Loop Quantum Cosmology: A Status Report
Abhay Ashtekar,Parampreet Singh +1 more
TL;DR: An overview of the current state of the art in loop quantum cosmology for three sets of audiences is given in this article, including young researchers interested in entering this area, the quantum gravity community in general, and cosmologists who wish to apply loop quantum Cosmology to probe modifications in the standard paradigm of the early universe.
Journal ArticleDOI
Hamiltonian cosmological perturbation theory with loop quantum gravity corrections
TL;DR: In this article, the authors derived cosmological perturbation equations in a canonical scheme based on Ashtekar variables and compared with the covariant derivation and various subtleties in the calculation and choice of gauges.
Journal ArticleDOI
Quantization ambiguities and bounds on geometric scalars in anisotropic loop quantum cosmology
TL;DR: In this paper, it was shown that using open holonomies of the extrinsic curvature, which due to gauge-fixing can be treated as a connection, leads to the same quantum geometry effects that are found in spatially flat cosmologies.
Journal ArticleDOI
Numerical evolution of squeezed and non-Gaussian states in loop quantum cosmology
TL;DR: In this article, the authors used the Chimera scheme for the spatially flat, homogeneous and isotropic model sourced with a massless scalar field and demonstrated that the quantum bounce in this model occurs even for states that are highly squeezed or are non-Gaussian with multiple peaks and with little resemblance to semi-classical states.
