Investigation of the gravitational dust collapse of the LQG-inspired effective asymmetric bounce model
Kristina Giesel, Hongguang Liu, Eric Rullit
We investigate gravitational dust collapse within an effective loop quantum gravity (LQG)-inspired model exhibiting an asymmetric bounce in the marginally bound case. This work ext…
From Principles to Effective Models: A Constructive Framework for Effective Covariant Actions with a Unique Vacuum Solution
Kristina Giesel, Hongguang Liu
The absence of Birkhoff's theorem in effective quantum gravity models leads to a fundamental ambiguity in the vacuum sector, where a priori no unique vacuum solution exists. As a r…
Regular black holes and their relationship to polymerized models and mimetic gravity
Kristina Giesel, Hongguang Liu, Parampreet Singh +1
We present further applications of the formalism introduced by the authors in arXiv:2308.10949, which allows embedding of a broad class of generalized LTB models into effective sph…
Polymer Schwarzschild black hole: An effective metric
Jibril Ben Achour, Frédéric Lamy, Hongguang Liu +1
We consider the modified Einstein equations obtained in the framework of effective spherically symmetric polymer models inspired by Loop Quantum Gravity. When one takes into accoun…
