Loop Quantum Cosmology: Recent Progress [PDF]
Pramana, 2004 Aspects of the full theory of loop quantum gravity can be studied in a simpler context by reducing to symmetric models like cosmological ones. This leads to several applications where loop effects play a significant role when one is sensitive to the ...

Tomography in loop quantum cosmology [PDF]
The European Physical Journal Plus, 2021 We analyze the tomographic representation for the Friedmann–Robertson–Walker (FRW) model within the Loop Quantum Cosmology framework. We focus on the Wigner quasi-probability distributions associated with Gaussian and Schrödinger cat states, and then, by

Thermodynamics in Loop Quantum Cosmology [PDF]
Advances in High Energy Physics, 2009 Loop quantum cosmology (LQC) is very powerful to deal with the behavior of early universe. Moreover, the effective loop quantum cosmology gives a successful description of the universe in the semiclassical region.

Proceedings of 3rd Quantum Gravity and Quantum Geometry School — PoS(QGQGS 2011), 2013 This Chapter provides an up to date, pedagogical review of some of the most relevant advances in loop quantum cosmology. We review the quantization of homogeneous cosmological models, their singularity resolution and the formulation of effective ...

Isotropic Loop Quantum Cosmology [PDF]
Classical and Quantum Gravity, 2002 Isotropic models in loop quantum cosmology allow explicit calculations, thanks largely to a completely known volume spectrum, which is exploited in order to write down the evolution equation in a discrete internal time.

Observational constraints on warm inflation in loop quantum cosmology [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 By incorporating quantum aspects of gravity, Loop Quantum Cosmology (LQC) provides a self-consistent extension of the inflationary scenario, allowing for modifications in the primordial inflationary power spectrum with respect to the standard General ...

Effective Field Theory of Loop Quantum Cosmology [PDF]
Universe, 2019 Quantum cosmology is traditionally formulated in a minisuperspace setting, implicitly averaging fields over space to obtain homogeneous models. For universal reasons related to the uncertainty principle, quantum corrections then depend on the size of the

A Brief Introduction to Loop Quantum Cosmology [PDF]
AIP Conference Proceedings, 2009 In recent years, Loop Quantum Gravity has emerged as a solid candidate for a nonperturbative quantum theory of General Relativity. It is a background independent theory based on a description of the gravitational field in terms of holonomies and fluxes ...

Unveiling the evolution of rotating black holes in loop quantum cosmology [PDF]
Scientific ReportsIn this work, we aim to discuss about the evolution of rotating black holes (RBHs) within the context of loop quantum cosmology. Here, the main part of our research work focuses on the impacts of angular momentum based rotating parameter and accretion ...

Unimodular Loop Quantum Cosmology [PDF]
Physical Review D, 2010 Unimodular gravity is based on a modification of the usual Einstein-Hilbert action that allows one to recover general relativity with a dynamical cosmological constant.
