On the flux vacua in F-theory compactifications
We study moduli stabilization of the F-theory compactified on an elliptically fibered Calabi–Yau fourfold. Our setup is based on the mirror symmetry framework including brane deformations.

Special points of inflation in flux compactifications
We study the realization of axion inflation models in the complex structure moduli spaces of Calabi–Yau threefolds and fourfolds. The axions arise close to special points of these moduli spaces that admit discrete monodromy symmetries of infinite order ...

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.

Calabi-Yau period geometry and restricted moduli in Type II compactifications [PDF]
The period geometry of Calabi-Yau n-folds — characterised by their variations of Hodge structure governed by Griffiths transversality, a graded Frobenius algebra, an integral monodromy and an intriguing arithmetic structure — is analysed for applications

Aspects of finite temperature corrections in string theory [PDF]
PhDIn this thesis some aspects of temperature corrections in string theory are analyzed: in particular, we study the thermal contributions to the 4 dimensional effective potential arising from string theory compactifications.

Exceptional flux compactifications [PDF]
AbstractWe consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gaugedD= 4 supergravity. This enables one to investigate the critical points, mass spectra and gauge groups of such backgrounds.

Comments on heterotic flux compactifications [PDF]
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.

Dynamics of warped flux compactifications [PDF]
We discuss the four dimensional effective action for type IIB flux compactifications, and obtain the quadratic terms taking warp effects into account. The analysis includes both the 4-d zero modes and their KK excitations, which become light at large warping.
