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…
On consistent gauge fixing conditions in polymerized gravitational systems
Kristina Giesel, Bao-Fei Li, Parampreet Singh +1
For classical gravitational systems the lapse function and the shift vector are usually determined by imposing appropriate gauge fixing conditions and then demanding their preserva…
