Description

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 access to both the local and non-local interactions appearing in the effective description. As a first application we discuss the partial reconstruction of the quantum effective action from correlation functions obtained within the Causal Dynamical Triangulations program.
