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 $SO(10)\times U(1)$ model in six dimensions compactified on the orbifold $T^2/{\mathbb Z_2}$ with ...

Compactifications of Type II supergravities in superspace [PDF]
We propose a way to describe compactifications of Type II supergravities with fluxes directly from superspace. The on-shell supergravity constraints used are the ones that arise naturally from the pure spinor superstring.

Type IIB flux compactifications with h 1,1 = 0 [PDF]
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 $$ \mathcal{N} $$

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.

Maximal supergravity from IIB flux compactifications [PDF]
Using a recently proposed group-theoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without stationary points.
