Moduli stabilization in asymptotic flux compactifications

open access: yesJournal 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 ...

Universal axion backreaction in flux compactifications

open access: yesJournal 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

open access: yesJournal 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.

Asymptotic flux compactifications and the swampland

open access: yesJournal 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.

đť’© = 1 SCFTs from F-theory on Orbifolds

open access: yesJournal of High Energy Physics, 2023
We study four-dimensional superconformal field theories living on the worldvolume of D3 branes probing minimally-supersymmetric F-theory backgrounds, focusing on the case of orbi-orientifold setups with and without 7-branes.

Compactifications of ADE conformal matter on a torus

open access: yesJournal of High Energy Physics, 2018
In this paper we study compactifications of ADE type conformal matter, N M5 branes probing ADE singularity, on torus with flux for global symmetry. We systematically construct the four dimensional theories by first going to five dimensions and studying ...

Conifold Transitions in M-theory on Calabi-Yau Fourfolds with Background Fluxes [PDF]

open access: yes, 2012
We consider topology changing transitions for M-theory compactifications on Calabi-Yau fourfolds with background G-flux. The local geometry of the transition is generically a genus g curve of conifold singularities, which engineers a 3d gauge theory with

Lobotomy of Flux Compactifications [PDF]

open access: yes, 2014
We provide the dictionary between four-dimensional gauged supergravity and type II compactifications on $\mathbb{T}^6$ with metric and gauge fluxes in the absence of supersymmetry breaking sources, such as branes and orientifold planes.

No-go theorems for ekpyrosis from ten-dimensional supergravity

open access: yesJournal of High Energy Physics, 2018
In this note we investigate whether the new ekpyrotic scenario can be embedded into ten-dimensional supergravity. We use that the scalar potential obtained from flux compactifications of type II supergravity with sources has a universal scaling with ...

Nothing is certain in string compactifications

open access: yesJournal of High Energy Physics, 2020
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.
