Moduli stabilization in asymptotic flux compactifications [PDF]
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 ...

Geometric Algebra Techniques in Flux Compactifications [PDF]
We study “constrained generalized Killing (s)pinors,” which characterize supersymmetric flux compactifications of supergravity theories. Using geometric algebra techniques, we give conceptually clear and computationally effective methods for translating ...

Flux compactifications and naturalness [PDF]
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.

Automated consistent truncations and stability of flux compactifications [PDF]
Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures.

Universal axion backreaction in flux compactifications [PDF]
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.

Asymptotic flux compactifications and the swampland [PDF]
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.

Meromorphic flux compactification [PDF]
We present exact solutions of four-dimensional Einstein’s equations related to Minkoswki vacuum constructed from Type IIB string theory with non-trivial fluxes.

Resolving spacetime singularities in flux compactifications & KKLT [PDF]
In flux compactifications of type IIB string theory with D3 and seven-branes, the negative induced D3 charge localized on seven-branes leads to an apparently pathological profile of the metric sufficiently close to the source.

Proton decay in flux compactifications
We study proton decay in a six-dimensional orbifold GUT model with gauge group SO(10)×U(1) A . Magnetic U(1) A flux in the compact dimensions determines the multiplicity of quark-lepton generations, and it also breaks supersymmetry by giving universal ...

A worldsheet description of flux compactifications
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.
