Loop Quantum Cosmology: Physics of Singularity Resolution and its Implications

, 2023
The occurrence of singularities where spacetime curvature becomes infinite and geodesic evolution breaks down are inevitable events in classical general relativity (GR) unless one chooses an exotic matter violating weak energy condition.

Initial conditions of pre-inflation with Hilltop potential in loop quantum cosmology

General Relativity and Gravitation, 2021
In this paper, we investigate the dynamics of pre-inflation with Hilltop potential in the framework of loop quantum cosmology. The initial conditions of inflaton field at the quantum bounce is categorized into two classes, first one is dominated by ...

Quantum general relativity

, 2015
EINSTEIN’S reservations on foundations of quantum mechanics are well-known. However, being a founding father of that subject, he was well-aware of the limitation of classical theories and emphasized, already in 1916, that quantum theory would have to ...

A Quantum-Cosmological Equation for the Regularization of Singularities and the Unification of Quantum Mechanics and General Relativity

This paper presents a novel quantum-cosmological equation aimed at addressing the singularity problem in general relativity by introducing quantum corrections. The equation seeks to unify quantum mechanics and general relativity, offering a pathway for the regularization of singularities in black holes and the early universe.

Extra-Dimensional de Broglie-Bohm Quantum Cosmology

General Relativity and Gravitation
In this work, we explore the de Broglie-Bohm Quantum Cosmology for a stiff matter, $p = \rho$, anisotropic n-dimensional Universe. One begins by considering a Gaussian wave function for the Universe, which depends on the momenta parameters $q_1$ and $q_2$

Limiting curvature mimetic gravity and its relation to Loop Quantum Cosmology

General Relativity and Gravitation, 2018
Considering as usual that the underlying geometry of our universe is well described by the spatially flat Friedmann–Lemaître–Robertson–Walker line element, we review how the background of holonomy corrected Loop Quantum Cosmology (LQC) could be obtained ...
