Exact Flux Vacua, Symmetries, and the Structure of the Landscape
Thomas W. Grimm, Damian van de Heisteeg
Identifying flux vacua in string theory with stabilized complex structure moduli presents a significant challenge, necessitating the minimization of a scalar potential complicated…
Finiteness Theorems and Counting Conjectures for the Flux Landscape
Thomas W. Grimm, Jeroen Monnee
In this paper, we explore the string theory landscape obtained from type IIB and F-theory flux compactifications. We first give a comprehensive introduction to a number of mathemat…
The Tameness of Quantum Field Theory, Part II -- Structures and CFTs
Michael R. Douglas, Thomas W. Grimm, Lorenz Schlechter
Tame geometry originated in mathematical logic and implements strong finiteness properties by defining the notion of tame sets and functions. In part I we argued that observables i…
Bi-Yang-Baxter Models and Sl(2)-orbits
Thomas W. Grimm, Jeroen Monnee
We study integrable deformations of two-dimensional non-linear sigma-models and present a new class of classical solutions to critical bi-Yang-Baxter models for general groups. For…
Global symmetry-breaking and generalized theta-terms in Type IIB EFTs
Thomas W. Grimm, Stefano Lanza, Thomas van Vuren
A longstanding conjecture states that global symmetries should be absent in quantum gravity. By investigating large classes of Type IIB four-dimensional effective f…
The Tameness of Quantum Field Theory, Part I -- Amplitudes
Michael R. Douglas, Thomas W. Grimm, Lorenz Schlechter
We propose a generalized finiteness principle for physical theories, in terms of the concept of tameness in mathematical logic. A tame function or space can only have a finite amou…
Tameness, Strings, and the Distance Conjecture
Thomas W. Grimm, Stefano Lanza, Chongchuo Li
The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field space. We argue that the inherent pa…
The Tadpole Conjecture in Asymptotic Limits
Mariana Graña, Thomas W. Grimm, Damian van de Heisteeg +2
The tadpole conjecture suggests that the complete stabilization of complex structure deformations in Type IIB and F-theory flux compactifications is severely obstructed by the tadp…
Taming the Landscape of Effective Theories
Thomas W. Grimm
We introduce a generalized notion of finiteness that provides a structural principle for the set of effective theories that can be consistently coupled to quantum gravity. More con…
Moduli Stabilization in Asymptotic Flux Compactifications
Thomas W. Grimm, Erik Plauschinn, Damian van de Heisteeg
We present a novel strategy to systematically study complex-structure moduli stabilization in Type IIB and F-theory flux compactifications. In particular, we determine vacua in any…
Deformed WZW Models and Hodge Theory -- Part I
Thomas W. Grimm, Jeroen Monnee
We investigate a relationship between a particular class of two-dimensional integrable non-linear -models and variations of Hodge structures. Concretely, our aim is to study the…
Engineering Small Flux Superpotentials and Mass Hierarchies
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
We study the stabilization of complex structure moduli in Type IIB flux compactifications by using recent general results about the form of the superpotential and Kähler potential…
Modeling General Asymptotic Calabi-Yau Periods
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
In the quests to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures we initiate the general study of asymptotic period vectors of Cala…
Bulk Reconstruction in Moduli Space Holography
Thomas W. Grimm, Jeroen Monnee, Damian van de Heisteeg
It was recently suggested that certain UV-completable supersymmetric actions can be characterized by the solutions to an auxiliary non-linear sigma-model with special asymptotic bo…
Universal Axion Backreaction in Flux Compactifications
Thomas W. Grimm, Chongchuo Li
We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same multiplet. Such configurations are relevant in attempts…
Weak Gravity Bounds in Asymptotic String Compactifications
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
We study the charge-to-mass ratios of BPS states in four-dimensional supergravities arising from Calabi-Yau threefold compactifications of Type IIB string theory. W…
Moduli Space Holography and the Finiteness of Flux Vacua
Thomas W. Grimm
A holographic perspective to study and characterize field spaces that arise in string compactifications is suggested. A concrete correspondence is developed by studying two-dimensi…
Classifying Calabi-Yau threefolds using infinite distance limits
Thomas W. Grimm, Fabian Ruehle, Damian van de Heisteeg
We present a novel way to classify Calabi-Yau threefolds by systematically studying their infinite volume limits. Each such limit is at infinite distance in Kahler moduli space and…
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…
Infinite Distances and the Axion Weak Gravity Conjecture
Thomas W. Grimm, Damian van de Heisteeg
The axion Weak Gravity Conjecture implies that when parametrically increasing the axion decay constants, instanton corrections become increasingly important. We provide strong evid…
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 Distance Networks in Field Space and Charge Orbits
Thomas W. Grimm, Chongchuo Li, Eran Palti
The Swampland Distance Conjecture proposes that approaching infinite distances in field space an infinite tower of states becomes exponentially light. We study this conjecture for…
Four-dimensional black hole entropy from F-theory
Thomas W. Grimm, Huibert het Lam, Kilian Mayer +1
We study the central charges and levels of a two-dimensional superconformal field theory describing four-dimensional BPS black holes in F-theory. These arise from D3-bran…
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…
