Coupling matter to loop quantum gravity
… die Vorhersagen solcher Effekte im Rahmen der Loop-Quantengravitation verwendet werden können. Dazu wird als Modellsystem ein skalares Feld, gekoppelt an das Gravitationsfeld, betrachtet. Zunächst wird unter bestimmten Annahmen über die Dynamik des gekoppelten Systems eine Quantentheorie für …

The Methodology of Loop Quantum Gravity
… of the quantization method used to formulate Loop Quantum Gravity, a proposed quantum theory of gravity developed in recent years from the quantization of General Relativity in connection variables. Loop Quantum Gravity is known to have the property of background independence in contrary to …

Effective loop quantization of black holes : a comparative analysis of quantization schemes.
Loop quantization of spherically symmetric black hole (BH) spacetimes has quantization ambiguities stemming from the choices (schemes) of the two polymerization parameters that characterize quantum corrections in effective loop quantum gravity (LQG). In this dissertation we systematically carry out …

Unusual Matter Models in Cosmology
… bases, including bulk viscous cosmology, loop quantum gravity, k-essence, and brane-world cosmologies. We find a range of exact solutions for isotropic universes, discuss their behaviours with reference to the early- and late-time evolution, accelerated expansion, and the occurrence or …

The Legendre Transform of the Holst Action
I start with a short introduction on 3+1 ADM form and the tetrad form of General Relativity, then I review the Legendre transform of the Einstein-Hilbert action and the Palatini action. The Holst action is a generalization of the Palatini action by including a topological term. I derive Ashtekar's …
