We give a brief review of our previous works.1,2 We discuss two sets of issues. The first has to do with the possibility of getting a non-supersymmetric dS minimum without the addition of $\overline{D3}$-branes as in KKLT, and axionic slow-roll inflation, in type II flux compactifications. The second has to do with the "Inverse Problem"3 and "Fake Superpotentials"4 for extremal (non)supersymmetric black holes in type II compactifications. We use (orientifold of) a "Swiss Cheese" Calabi–Yau5…

Moduli thermalization and finite temperature effects in “big” divisor large volume D3/D7 Swiss-cheese compactification

In the context of Type IIB compactified on a large volume Swiss-Cheese orientifold in the presence of a mobile space-time filling D3-brane and stacks of fluxed D7-branes wrapping the “big” divisor ΣB



Flux Compactifications on Calabi-Yau Threefolds

The presence of RR and NS three-form fluxes in type IIB string compactification on a Calabi-Yau orientifold gives rise to a nontrivial superpotential W for the dilaton and complex structure moduli.

Area Codes, Large Volume (Non-)Perturbative alpha'- and Instanton - Corrected Non-supersymmetric (A)dS minimum, the Inverse Problem and Fake Superpotentials for Multiple-Singular-Loci-Two-Parameter Calabi-Yau's

We consider two sets of issues in this paper. The first has to do with moduli stabilization, existence of " area codes " [1] and the possibility of getting a non-supersymmetric dS minimum without the

Systematics of moduli stabilisation in Calabi-Yau flux compactifications

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

De Sitter vacua in string theory

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes. By

Racetrack Inflation

: We develop a model of eternal topological inflation using a racetrack potential within the context of type IIB string theory with KKLT volume stabilization. The inflaton field is the imaginary part of

Supersymmetry Breaking and α′-Corrections to Flux Induced Potentials

We obtain the vacuum solutions for M-theory compactified on eight-manifolds with non-vanishing four-form flux by analyzing the scalar potential appearing in the three-dimensional theory. Many of

Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking

We present an explicit calculation of the spectrum of a general class of string models, corresponding to Calabi-Yau flux compactifications with h1,2 > h1,1 > 1 with leading perturbative and

Non-supersymmetric attractors

We consider theories with gravity, gauge fields and scalars in four-dimensional asymptotically flat space-time. By studying the equations of motion directly we show that the attractor mechanism can
