Description
A great success from Quantum Field Theory methods lies in their ability to directly obtain the effective theory, where all degrees of freedom have been integrated out, starting from a UV-complete framework.
We adopt a new approach to combine path integral effective methods and Loop Quantum Gravity (LQG) by using the recently developed coherent state path integral formulation of LQG to compute the one-loop effective action. We highlight the differences between our approach and the standard Feynman-prescribed path integral. This investigation has two main objectives: to compare our findings with the divergences encountered in the one-loop calculations of Einstein gravity and to begin exploring the IR effective properties of LQG.
Based on work in collaboration with Muxin Han and Hongguang Liu.
