dc.description.abstractQuantum Theory and General Relativity are two of the most successful theories of Nature in their respective regimes. In situations where effects from both are non-negligible, the regime of Quantum Gravity emerges. Many theories, such as String Theory, Loop Quantum Gravity and Doubly Special Relativity, attempt to address the high-energy regime of Quantum Gravity. The structures of such theories suggest the existence of a minimum measurable length. This in turn modifies the Heisenberg Uncertainty Principle, to the so-called Generalized Uncertainty Principle (GUP). In this work, GUP is used to construct phenomenological models, which can be used to verify the existence of a minimum measurable length. Specifically, in Earth-based experiments, the magnetometer experiment and Bose-Einstein condensation are considered, and in cosmology, explanations of the baryon asymmetry in the Universe and the EDGES anomaly are provided. Furthermore, a novel conceptual approach to Quantum Gravity, namely the Quantum Equivalence Principle, is explored.
