A worldsheet description of flux compactifications [PDF]
Journal of High Energy Physics, 2023 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 [PDF]
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 ...

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.

Proton decay in flux compactifications [PDF]
Journal of High Energy Physics, 2019 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 ...

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.

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.

Automated consistent truncations and stability of flux compactifications [PDF]
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 [PDF]
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 $$ \mathcal{N} $$

Resolving spacetime singularities in flux compactifications & KKLT [PDF]
Journal of High Energy Physics, 2021 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.

Exceptional Flux Compactifications [PDF]
Journal of High Energy Physics, 2012 We consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gauged D=4 supergravity.
