Nongeometric Flux Compactifications [PDF]
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.

Threshold corrections in heterotic flux compactifications [PDF]
We compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of N = 2 $$ \mathcal{N}=2 $$ non-Kähler heterotic compactifications with three-form flux, consisting in principal two-torus bundles over K3 surfaces.

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 ...

Flavor mixings in flux compactifications [PDF]
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 $

Three-forms in supergravity and flux compactifications [PDF]
We present a duality procedure that relates conventional four-dimensional matter-coupled $$\mathcal{N}=1$$ N = 1 supergravities to dual formulations in which auxiliary fields are replaced by field strengths of gauge three-forms.

Comments on Heterotic Flux Compactifications [PDF]
In heterotic flux compactification with supersymmetry, three different connections with torsion appear naturally, all in the form $\omega+a H$. Supersymmetry condition carries $a=-1$, the Dirac operator has $a=-1/3$, and higher order term in the ...

Warping the Kähler potential of F-theory/IIB flux compactifications [PDF]
We identify the low-energy Kähler potential of warped F-theory/IIB flux compactifications whose light spectrum includes universal, Kähler, axionic and mobile D3-brane moduli.

Flux compactifications in string theory: a comprehensive review [PDF]
We present a pedagogical overview of flux compactifications in string theory, from the basic ideas to the most recent developments. We concentrate on closed string fluxes in type II theories.

Maximal Temperature in Flux Compactifications [PDF]
Thermal corrections have an important effect on moduli stabilization leading to the existence of a maximal temperature, beyond which the compact dimensions decompactify. In this note, we discuss generality of our earlier analysis and apply it to the case
