Although perturbatively non-renormalizable, general relativity is a perfectly valid quantum theory at low energies. Treated as an effective field theory one is able to make genuine quantum predictions by applying the conventional rules of quantum field theory. The low energy degrees of freedom and couplings of quantum gravity are fully dictated by the symmetries of general relativity. At long...

By definition, the quantum effective action describes the dynamics of a theory taking all quantum effects into account. Conceptually, it may provide an important bridge between the fundamental description of gravity and its phenomenological consequences. This talk outlines a new approach to construct the quantum effective action for gravity based on correlation functions. This approach gives...
