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.

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.

Lobotomy of Flux Compactifications [PDF]

Journal of High Energy Physics, 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.

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.

Nongeometric Flux Compactifications [PDF]

Journal of High Energy Physics, 2005
We investigate a simple class of type II string compactifications which incorporate nongeometric "fluxes" in addition to "geometric flux" and the usual H-field and R-R fluxes. These compactifications are nongeometric analogues of the twisted torus.

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 ...

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.

Meromorphic flux compactification [PDF]

Journal of High Energy Physics, 2017
We present exact solutions of four-dimensional Einstein’s equations related to Minkoswki vacuum constructed from Type IIB string theory with non-trivial fluxes.

Flavour mixings in flux compactifications [PDF]

Physical Review D, 2017
A multiplicity of quark-lepton families can naturally arise as zero-modes in flux compactifications. The flavour structure of quark and lepton mass matrices is then determined by the wave function profiles of the zero-modes. We consider a supersymmetric $

Geometric Algebra Techniques in Flux Compactifications [PDF]

Advances in High Energy Physics, 2016
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 ...
