Quantum Gravity at the Crossroads: Asymptotic Safety, Effective Field Theory, and the Swampland
Quantum gravity remains fragmented across scales and frameworks: in the UV, a number of alternative theories aim to describe the fundamental aspects of gravity; in the IR, EFT considerations and observations can constrain beyond-GR physics in a theory-agnostic fashion. Rather than treating these domains as separate, I will argue for a unifying approach: by extending the logic of the swampland program, one can attempt to map UV theories into the corresponding “landscapes” of EFTs, thus establishing a common language to compare different quantum-gravity frameworks among each other and with IR constraints. In this talk, I will use this approach to illustrate how ideas from Asymptotic Safety, the Swampland Program, and EFT can inform and challenge each other.
