The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

A bstract We argue that in theories of quantum gravity with discrete gauge symmetries, eg Z
k, the gauge couplings of U (1) gauge symmetries become weak in the limit of large k, as g→ …

Motivated by its potential use as a starting point for solving various cosmological constant
problems, we study F‐theory compactified on the warped product where Y8 is a manifold …

A bstract We consider string theory vacua with tadpoles for dynamical fields and uncover
universal features of the resulting spacetime-dependent solutions. We argue that the …

A bstract We propose a new version of the scalar Weak Gravity Conjecture (WGC) which
would apply to any scalar field coupled to quantum gravity. For a single scalar it is given by …

A bstract We show that warped throats of the Klebanov-Strassler kind, regarded as 5d flux
compactifications on Sasaki-Einstein manifolds X 5, describe fully backreacted solutions of …

We study the phenomenology of a recent string construction with a quantum mechanically
stable dark energy. A mild supersymmetry protects the vacuum energy but also allows TeV …

A bstract Recent string theory tests of swampland ideas like the distance or the dS
conjectures have been performed at weak coupling. Testing these ideas beyond the weak …

We describe the construction of large classes of explicit string theory backgrounds
corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe …

A bstract The swampland program of delineating the space of effective field theories
consistent with quantum gravity appears similar to the bootstrap program of delineating the …
