The paper of Kristina Giesel, Hongguang Liu, Parampreet Singh and Stefan Weigl was recently accepted by Physical Review D. The paper This article contains further applications of the formalism developed in our previous work in Phys.Rev.D 110 (2024) 10, 104017, with a particular focus on regular black holes models as a special case of polymerised LTB solutions. One result of this work is that the Birkhoff theorem in classical general relativity is generalised to a certain class of models for regular black holes, for which a similar uniqueness result can be achieved in LTB coordinates, while the situation in Schwarzschild-like coordinates is more subtle. Furthermore, a general reconstruction algorithm has been introduced that allows one to start from a given model in a Schwarzschild-like metric and to reconstruct the underlying effective spherically symmetric model, which can then be extended to general inhomogeneous dust collapse models. Furthermore, it allows these models to be linked to extended mimetic gravity models by suitably choosing the mimetic potential. This was applied not only to LQG-inspired polymerisations, but also to other prominent solutions for regular black holes, such as Bardeen and Hayward. The arXiv version of the paper can be found here e-Print: 2405.03554 [gr-qc].
