@article{Bautista2018NonlocalQE, title={Nonlocal quantum effective actions in Weyl-Flat spacetimes}, author={Teresa Bautista and Andr'e Benevides and Atish Dabholkar}, journal={Journal of High Energy Physics}, year={2018}, volume={2018}, pages={1-25} }

A bstractVirtual massless particles in quantum loops lead to nonlocal effects which can have interesting consequences, for example, for primordial magnetogenesis in cosmology or for computing finite N corrections in holography. We describe how the quantum effective actions summarizing these effects can be computed efficiently for Weyl-flat metrics by integrating the Weyl anomaly or, equivalently, the local renormalization group equation. This method relies only on the local Schwinger-DeWitt…
