Weakly-coupled IIA flux compactifications [PDF]
Journal of High Energy Physics, 2008 We study compactifications of type IIA string theory on Calabi-Yau manifolds that are mirror to a subset of the type IIB LARGE-volume models. A combination of flux, alpha' corrections and non-perturbative effects stabilises the moduli in a non-supersymmetric AdS vacuum.

Comments on heterotic flux compactifications [PDF]
Journal of High Energy Physics, 2006 In heterotic flux compactification with supersymmetry, three different connections with torsion appear naturally, all in the form $ +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.

Flavor mixings in flux compactifications [PDF]
Physical Review D, 2017 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 ...

M-theory compactification, fluxes, and
, 2005 We analyze supersymmetric solutions of M-theory based an a seven-dimensional internal space with SU(3) structure and a four-dimensional maximally symmetric space. The most general supersymmetry conditions are derived and we show that a non-vanishing cosmological constant requires the norms of the two internal spinors to differ.

𝒩 = 1 SCFTs from F-theory on Orbifolds
Journal 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.

Compactifications of ADE conformal matter on a torus
Journal of High Energy Physics, 2018 In this paper we study compactifications of ADE type conformal matter, N M5 branes probing ADE singularity, on torus with flux for global symmetry. We systematically construct the four dimensional theories by first going to five dimensions and studying ...

Maximal supergravity from IIB flux compactifications [PDF]
Physics Letters B, 2004 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.
