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.
TLDR
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.
Mass hierarchies and dynamical field range
Several swampland conjectures suggest that there is a critical field range beyond which the effective field theory (EFT) description breaks down in quantum gravity. In applications of these
Are tiny gauge couplings out of the Swampland?
A bstractThere is significant evidence suggesting that continuous global symmetries are always gauged in quantum gravity. However, very weakly gauged symmetries seem global to an effective field
The weak gravity conjecture and scalar fields
A bstractWe propose a generalisation of the Weak Gravity Conjecture in the presence of scalar fields. The proposal is guided by properties of extremal black holes in N=2$$ \mathcal{N}=2 $$

We propose a generalisation of the Weak Gravity Conjecture in the presence of scalar fields. The proposal is guided by properties of extremal black holes in N = 2 supergravity, but can be understood
Gauge and gravitational instantons: from 3-forms and fermions to weak gravity and flat axion potentials
Abstract We investigate the role of gauge and gravitational instantons in the context of the Swampland program. Our focus is on the global symmetry breaking they induce, especially in the presence
Scalar fields, hierarchical UV/IR mixing and the Weak Gravity Conjecture
A bstractThe Weak Gravity Conjecture (WGC) bounds the mass of a particle by its charge. It is expected that this bound can not be below the ultraviolet cut-off scale of the effective theory.

Abstract In effective quantum field theory, a spin-1 vector boson can have a technically natural small mass that does not originate from the Higgs mechanism. For such theories, which may be
The Swampland Spectrum Conjecture in Inflation
The quantum gravity conjectures that aim to separate the landscape from the swampland among the low energy theories were originally formulated in the context of scalar field spaces spanned by moduli.
