The extreme conditions of the early universe require to be studied taking into account both Quantum Mechanics and General Relativity. Loop Quantum Gravity is one of the main approaches to the quantization of gravity. In this framework, the quantum nature of the geometry removes the classical Big Bang singularity, that is replaced by a Big Bounce. The theory permits to define a general covariant path-integral (spinfoam), that contains the information about the quantum fluctuations of the geometry. This path integral can be studied beyond the usual pertubative approach. This research project starts the study of the quantum geometry at the bounce, and hopefully of the origin of structures formation.", "summary_en": "The origin of quantum fluctuations, from which cosmic structures come from, is one of the most important open questions of contemporary cosmology.
