Living Reviews in Relativity, 2008 Quantum gravity is expected to be necessary in order to understand situations in which classical general relativity breaks down. In particular in cosmology one has to deal with initial singularities, i.e., the fact that the backward evolution of a ...

Loop quantum cosmology and singularities [PDF]
Scientific Reports, 2017 Loop quantum gravity is believed to eliminate singularities such as the big bang and big crunch singularity. This belief is based on studies of so-called loop quantum cosmology which concerns symmetry-reduced models of quantum gravity. In this paper, the

Testing loop quantum cosmology [PDF]
, 2017 Loop quantum cosmology predicts that quantum gravity effects resolve the big-bang singularity and replace it by a cosmic bounce. Furthermore, loop quantum cosmology can also modify the form of primordial cosmological perturbations, for example by ...

Noncommutativity in Effective Loop Quantum Cosmology
Advances in High Energy Physics, 2019 We construct a noncommutative extension of the Loop Quantum Cosmology effective scheme for the flat FLRW model with a free scalar field via a theta deformation.

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 ...

Generic absence of strong singularities and geodesic completeness in modified loop quantum cosmologies [PDF]
, 2019 Different regularizations of the Hamiltonian constraint in loop quantum cosmology yield modified loop quantum cosmologies, namely mLQC-I and mLQC-II, which lead to qualitatively different Planck scale physics.

Mathematical Structure of Loop Quantum Cosmology: Homogeneous Models [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2013 The mathematical structure of homogeneous loop quantum cosmology is analyzed, starting with and taking into account the general classification of homogeneous connections not restricted to be Abelian.

European Physical Journal C: Particles and Fields, 2019 Mimetic gravity can be described as a formulation capable of mimicking different evolutionary scenarios regarding the universe dynamics. Notwithstanding its initial aim of producing a similar evolution to the one expected from the dark components of the ...

Loop Quantum Cosmology: Recent Progress [PDF]
, 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 ...
