A bstractThe recently proposed relaxion models require extremely large trans-Planckian axion excursions as well as a potential explicitly violating the axion shift symmetry. The latter property is however inconsistent with the axion periodicity, which corresponds to a gauged discrete shift symmetry. A way to make things consistent is to use monodromy, i.e. both the axion and the potential parameters transform under the discrete shift symmetry. The structure is better described in terms of a 3… 

Axion monodromy and the weak gravity conjecture

A bstractAxions with broken discrete shift symmetry (axion monodromy) have recently played a central role both in the discussion of inflation and the ‘relaxion’ approach to the hierarchy problem. We

The swampland conjecture and F-term axion monodromy inflation

A bstractWe continue the investigation of F-term axion monodromy inflation in string theory, while seriously taking the issue of moduli stabilization into account. For a number of closed and open

A bstractThe Weak Gravity Conjecture (WGC) demands the existence of superextremal particles in any consistent quantum theory of gravity. The standard lore is that these particles are introduced to

Flux flattening in axion monodromy inflation

A bstractString theory models of axion monodromy inflation exhibit scalar potentials which are quadratic for small values of the inflaton field and evolve to a more complicated function for large

Runaway relaxion monodromy

A bstractWe examine the relaxion mechanism in string theory. An essential feature is that an axion winds over N ≫ 1 fundamental periods. In string theory realizations via axion monodromy, this

Tensionless strings and the weak gravity conjecture

A bstractWe test various conjectures about quantum gravity for six-dimensional string compactifications in the framework of F-theory. Starting with a gauge theory coupled to gravity, we analyze the

Naturalizing supersymmetry with a two-field relaxion mechanism

A bstractWe present a supersymmetric version of a two-field relaxion model that naturalizes tuned versions of supersymmetry. This arises from a relaxion mechanism that does not depend on QCD dynamics

Infinite distances and the axion weak gravity conjecture

The axion Weak Gravity Conjecture implies that when parametrically increasing the axion decay constants, instanton corrections become increasingly important. We provide strong evidence for the

Is the relaxion an axion?

A bstractWe consider the recently proposed cosmological relaxation mechanism where the hierarchy problem is ameliorated, and the electroweak (EW) scale is dynamically selected by a slowly rolling

Fencing in the swampland: quantum gravity constraints on large field inflation

A bstractIn this note we show that models of natural inflation based on closed string axions are incompatible with the weak gravity conjecture (WGC). Specifically, we use T- duality in order to map

F-term axion monodromy inflation

A bstractThe continuous shift symmetry of axions is at the heart of several realizations of inflationary models. In particular, axion monodromy inflation aims at achieving super-Planckian field

A bstractWe discuss the role of Minkowski 3-forms in flux string vacua. In these vacua all internal closed string fluxes are in one to one correspondence with quantized Minkowski 4-forms. By
