Generalized analysis of a dust collapse in effective loop quantum gravity: fate of shocks and covariance

Kristina Giesel, Hongguang Liu, Parampreet Singh +1

Based on modifications inspired from loop quantum gravity (LQG), spherically symmetric models have recently been explored to understand the resolution of classical singularities an…

Embedding generalized LTB models in polymerized spherically symmetric spacetimes

Kristina Giesel, Hongguang Liu, Eric Rullit +2

We generalize the existing works on the way (generalized) LTB models can be embedded into polymerized spherically symmetric models in several aspects. We re-examine such an embeddi…

Quantum gravitational non-singular tunneling wavefunction proposal

Meysam Motaharfar, Parampreet Singh

It was recently shown that tunneling wavefunction proposal is consistent with loop quantum geometry corrections including both holonomy and inverse scale factor corrections in the…

Loop Quantum Cosmology: Physics of Singularity Resolution and its Implications

Bao-Fei Li, Parampreet Singh

The occurrence of singularities where spacetime curvature becomes infinite and geodesic evolution breaks down are inevitable events in classical general relativity (GR) unless one…

A diffeomorphism invariant family of metric-affine actions for loop cosmologies

Adrià Delhom, Gonzalo J. Olmo, Parampreet Singh

In loop quantum cosmology (LQC) the big bang singularity is generically resolved by a big bounce. This feature holds even when modified quantization prescriptions of the Hamiltonia…

Regular black holes from Loop Quantum Gravity

Abhay Ashtekar, Javier Olmedo, Parampreet Singh

There is rich literature on regular black holes from loop quantum gravity (LQG), where quantum geometry effects resolve the singularity, leading to a quantum extension of the class…
