A bstractWe study scenarios where a scalar field has a spatially varying vacuum expectation value such that the total field variation is super-Planckian. We focus on the case where the scalar field controls the coupling of a U(1) gauge field, which allows us to apply the Weak Gravity Conjecture to such configurations. We show that this leads to evidence for a conjectured property of quantum gravity that as a scalar field variation in field space asymptotes to infinity there must exist an…

Emergence of Weak Coupling at Large Distance in Quantum Gravity.

- PhysicsPhysical review letters

The Ooguri-Vafa swampland conjectures claim that in any consistent theory of quantum gravity, a tower of particles will become light at a rate that is exponential in the field-space distance, and this work provides a novel viewpoint on this claim.
