$G_2$ flux compactifications [PDF]

open access: green
We derive the three-dimensional $\mathcal{N}=1$ effective theories obtained by compactifying all five ten-dimensional string theories on generic seven-dimensional manifolds with $G_2$ structure. The resulting flux compactifications are worked out explicitly, including the full moduli dependence of the scalar potential, kinetic terms, axionic sectors ...

Comments on heterotic flux compactifications [PDF]

open access: yesJournal of High Energy Physics, 2006
In heterotic flux compactification with supersymmetry, three different connections with torsion appear naturally, all in the form $ω+a H$. Supersymmetry condition carries $a=-1$, the Dirac operator has $a=-1/3$, and higher order term in the effective action involves $a=1$. With a view toward the gauge sector, we explore the geometry with such torsions.

On flux compactification and moduli stabilization [PDF]

open access: yesPhysics Letters B, 2006
We study the effect of adding charged matter fields to both D3 and D7 branes in type IIB string theory compactification with fluxes. Generically, charged matter fields induce additional terms to the Kahler form, the superpotential and the D-terms. These terms allow for minima with positive or zero cosmological constants, even in the absence of non ...

Systematics of moduli stabilisation in Calabi-Yau flux compactifications [PDF]

open access: yes, 2005
We study the large volume limit of the scalar potential in Calabi-Yau flux compactifications of type IIB string theory. Under general circumstances there exists a limit in which the potential approaches zero from below, with an associated non ...

Dictionary for the type II nongeometric flux compactifications [PDF]

open access: yesPhysical Review D, 2019
We study the $T$-dual completion of the four-dimensional ${\cal N}=1$ type II effective potentials in the presence of (non-)geometric fluxes. First, we invoke a cohomology version of the $T$-dual transformations among the various moduli, axions and the ...

Warping the effective field theory of string flux compactifications [PDF]

open access: yes, 2022
Several phenomenological scenarios in string theory involve branes and fluxes, which are necessary in order to reproduce the proper gauge and matter sector and to provide a non-trivial potential for the so called moduli, scalars which are usually ...

Flux compactification

open access: yesReviews of Modern Physics, 2007
We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics.

Bubbles of nothing in flux compactifications [PDF]

open access: yesPhysical Review D, 2010
We construct a simple AdS_4 x S^1 flux compactification stabilized by a complex scalar field winding the extra dimension and demonstrate an instability via nucleation of a bubble of nothing. This occurs when the Kaluza -- Klein dimension degenerates to a point, defining the bubble surface. Because the extra dimension is stabilized by a flux, the bubble

𝒩 = 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.
