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…
Analysing (cosmological) singularity avoidance in loop quantum gravity using U coherent states and Kummer's functions
Kristina Giesel, David Winnekens
Using a new procedure based on Kummer's Confluent Hypergeometric Functions, we investigate the question of singularity avoidance in loop quantum gravity (LQG) in the context of U$(…
Non-singular quantum gravitational dynamics of an LTB dust shell model: the role of quantization prescriptions
Kristina Giesel, Bao-Fei Li, Parampreet Singh
We study some consequences of the loop quantization of the outermost dust shell in the Lemaître-Tolman-Bondi spacetime with a homogeneous dust density using different quantization…
