Asymptotic flux compactifications and the swampland [PDF]

Journal of High Energy Physics, 2020
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 fourfolds with four-form flux.

Universal axion backreaction in flux compactifications [PDF]

Journal of High Energy Physics, 2021
We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same N $$ \mathcal{N} $$ = 1 multiplet. Such configurations are relevant in attempts to realize axion monodromy inflation in string compactifications.

A worldsheet description of flux compactifications

Journal of High Energy Physics
We demonstrate how recent developments in string field theory provide a framework to systematically study type II flux compactifications with non-trivial Ramond-Ramond profiles.

Moduli stabilization in asymptotic flux compactifications

Journal of High Energy Physics, 2022
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 asymptotic regime of the complex-structure moduli space by exploiting ...

Flux compactifications and naturalness [PDF]

Journal of High Energy Physics, 2018
Free massless scalars have a shift symmetry. This is usually broken by gauge and Yukawa interactions, such that quantum corrections induce a quadratically divergent mass term.

Threshold corrections in heterotic flux compactifications

Journal of High Energy Physics, 2017
We compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of N = 2 $$ \mathcal{N}=2 $$ non-Kähler heterotic compactifications with three-form flux, consisting in principal two-torus bundles over K3 surfaces.

Automated consistent truncations and stability of flux compactifications

Journal of High Energy Physics, 2022
Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures.

Type IIB flux compactifications with h 1,1 = 0

Journal of High Energy Physics, 2022
We revisit flux compactifications of type IIB string theory on ‘spaces’ dual to rigid Calabi-Yau manifolds. This rather unexplored part of the string landscapes harbors many interesting four-dimensional solutions, namely supersymmetric N $$ \mathcal{N} $$

Nonlinear dynamics of flux compactification

Journal of High Energy Physics, 2021
We study the nonlinear evolution of unstable flux compactifications, applying numerical relativity techniques to solve the Einstein equations in D dimensions coupled to a q-form field and positive cosmological constant. We show that initially homogeneous

F-theory flux vacua and attractor equations

Journal of High Energy Physics, 2020
We examine the vacuum structure of 4D effective theories of moduli fields in spacetime compactifications with quantized background fluxes. Imposing the no-scale structure for the volume deformations, we numerically investigate the distributions of flux ...
