Loop quantum cosmology gravitational baryogenesis [PDF]
EPL (Europhysics Letters), 2016 Loop Quantum Cosmology is an appealing quantum completion of classical cosmology, which brings along various theoretical features which in many cases offer remedy or modify various classical cosmology aspects. In this paper we address the gravitational baryogenesis mechanism in the context of Loop Quantum Cosmology. As we demonstrate, when Loop Quantum

On the holographic basis of loop quantum cosmology
European Physical Journal C: Particles and Fields, 2018 In this work, we obtain the loop quantum cosmology dynamical equations, plus a positive cosmological constant, from the Bekenstein–Hawking entropy-area relation given by Loop Quantum Black Holes, by the use of the Jacobson formalism (Phys Rev Lett 75 ...

An Overview on the Nature of the Bounce in LQC and PQM
Universe, 2021 We present a review on some of the basic aspects concerning quantum cosmology in the presence of cut-off physics as it has emerged in the literature during the last fifteen years.

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. Because of genuinely quantum geometrical effects the classical singularity is absent in those models in the sense that the evolution ...

Gauge-Invariant Perturbations at a Quantum Gravity Bounce
Universe, 2022 We study the dynamics of gauge-invariant scalar perturbations in cosmological scenarios with a modified Friedmann equation, such as quantum gravity bouncing cosmologies.

Loop quantum cosmology: I. Kinematics [PDF]
Classical and Quantum Gravity, 2000 The framework of quantum symmetry reduction is applied to loop quantum gravity with respect to transitively acting symmetry groups. This allows to test loop quantum gravity in a large class of minisuperspaces and to investigate its features - e.g. the discrete volume spectrum - in certain cosmological regimes.

Loop quantum cosmology: an overview [PDF]
General Relativity and Gravitation, 2009 A brief overview of loop quantum cosmology of homogeneous isotropic models is presented with emphasis on the origin of and subtleties associated with the resolution of big bang and big crunch singularities. These results bear out the remarkable intuition that John Wheeler had. Discussion is organized at two levels.
