Light EFT Strings and Asymptotic Accelerated Expansion
Veronica Collazuol, Alessandra Grieco, Irene Valenzuela
We study the interplay among towers of particles, EFT strings, and EFT membranes near perturbative infinite-distance limits of four-dimensional theories. We show th…
Running Decompactification, Sliding Towers, and the Distance Conjecture
Muldrow Etheredge, Ben Heidenreich, Jacob McNamara +3
We study towers of light particles that appear in infinite-distance limits of moduli spaces of 9-dimensional string theories, some of which notably feature decompac…
Asymptotic Accelerated Expansion in String Theory and the Swampland
José Calderón-Infante, Ignacio Ruiz, Irene Valenzuela
We study whether the universal runaway behaviour of stringy scalar potentials towards infinite field distance limits can produce an accelerated expanding cosmology à la quintessenc…
Large Field Distances from EFT strings
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
In any consistent effective field theory of quantum gravity limits of infinite field distance are expected to lead to the EFT breakdown due to the appearance of an infinite tower o…
The Dark Dimension and the Swampland
Miguel Montero, Cumrun Vafa, Irene Valenzuela
Motivated by principles from the Swampland program, which characterize requirements for a consistent UV completion of quantum gravity, combined with observational data, we are led…
The Desert and the Swampland
Cody Long, Miguel Montero, Cumrun Vafa +1
The most natural expectation away from asymptotic limits in moduli space of supergravity theories is the desert scenario, where there are few states between massless fields and the…
Finiteness and the Swampland
Yuta Hamada, Miguel Montero, Cumrun Vafa +1
We view and provide further evidence for a number of Swampland criteria, including the Weak Gravity Conjecture, Distance Conjecture and bounds on the finiteness of the quantum grav…
Swampland Constraints on Neutrino Masses
E. Gonzalo, L. E. Ibáñez, I. Valenzuela
Compactifying the Standard Model (SM) on a circle may lead to AdS 3D vacua, depending on the character (Majorana or Dirac) and the mass of the lightest neutrino. It has been shown…
AdS Swampland Conjectures and Light Fermions
Eduardo Gonzalo, Luis E. Ibáñez, Irene Valenzuela
We consider constraints on -dimensional theories in , and backgrounds in the light of AdS swampland conjectures as applied to their compactification in a cir…
Non-Invertible Global Symmetries and Completeness of the Spectrum
Ben Heidenreich, Jacob McNamara, Miguel Montero +3
It is widely believed that consistent theories of quantum gravity satisfy two basic kinematic constraints: they are free from any global symmetry, and they contain a complete spect…
The EFT stringy viewpoint on large distances
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
We observe a direct relation between the existence of fundamental axionic strings, dubbed EFT strings, and infinite distance limits in 4d EFTs coupled to gravity. T…
Lectures on the Swampland Program in String Compactifications
Marieke van Beest, José Calderón-Infante, Delaram Mirfendereski +1
The Swampland program aims to determine the constraints that an effective field theory must satisfy to be consistent with a UV embedding in a quantum gravity theory. Different prop…
Chern-Weil Global Symmetries and How Quantum Gravity Avoids Them
Ben Heidenreich, Jacob McNamara, Miguel Montero +3
We draw attention to a class of generalized global symmetries, which we call "Chern-Weil global symmetries," that arise ubiquitously in gauge theories. The Noether currents of thes…
The Convex Hull Swampland Distance Conjecture and Bounds on Non-geodesics
José Calderón-Infante, Angel M. Uranga, Irene Valenzuela
The Swampland Distance Conjecture (SDC) restricts the geodesic distances that scalars can traverse in effective field theories as they approach points at infinite distance in modul…
A CFT Distance Conjecture
Eric Perlmutter, Leonardo Rastelli, Cumrun Vafa +1
We formulate a series of conjectures relating the geometry of conformal manifolds to the spectrum of local operators in conformal field theories in spacetime dimensions. We f…
de Sitter Bubbles and the Swampland
Alek Bedroya, Miguel Montero, Cumrun Vafa +1
A number of Swampland conjectures and in particular the Trans-Planckian Censorship Conjecture (TCC) suggest that de Sitter space is highly unstable if it exists at all. In this pap…
Swampland Conjectures for Strings and Membranes
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
Swampland criteria like the Weak Gravity Conjecture should not only apply to particles, but also to other lower-codimension charged objects in 4d EFTs like strings and membranes. H…
Nothing is certain in string compactifications
Iñaki García Etxebarria, Miguel Montero, Kepa Sousa +1
A bubble of nothing is a spacetime instability where a compact dimension collapses. After nucleation, it expands at the speed of light, leaving "nothing" behind. We argue that the…
Merging the Weak Gravity and Distance Conjectures Using BPS Extremal Black Holes
Naomi Gendler, Irene Valenzuela
We analyze the charge-to-mass structure of BPS states in general infinite-distance limits of compactifications of Type IIB string theory on Calabi-Yau three-folds,…
Asymptotic Flux Compactifications and the Swampland
Thomas W. Grimm, Chongchuo Li, Irene Valenzuela
We initiate the systematic study of flux scalar potentials and their vacua by using asymptotic Hodge theory. To begin with, we consider F-theory compactifications on Calabi-Yau fou…
Swampland Distance Conjecture, Inflation and -attractors
Marco Scalisi, Irene Valenzuela
The Swampland Distance Conjecture (SDC) constraints the dynamics emerging at infinite distances in field space of any effective field theory consistent with quantum gravity. It pro…
The Swampland Distance Conjecture for Kahler moduli
Pierre Corvilain, Thomas W. Grimm, Irene Valenzuela
The Swampland Distance Conjecture suggests that an infinite tower of modes becomes exponentially light when approaching a point that is at infinite proper distance in field space.…
Infinite Distances in Field Space and Massless Towers of States
Thomas W. Grimm, Eran Palti, Irene Valenzuela
It has been conjectured that in theories consistent with quantum gravity infinite distances in field space coincide with an infinite tower of states becoming massless exponentially…
Backreaction in Axion Monodromy, 4-forms and the Swampland
Irene Valenzuela
Axion monodromy models can always be described in terms of an axion coupled to 3-form gauge fields with non-canonical kinetic terms. The presence of the saxions parametrising the k…
