Hierarchies from Fluxes in String Compactifications
, 2002
"... Warped compactifications with significant warping provide one of the few known mechanisms for naturally generating large hierarchies of physical scales. We demonstrate that this mechanism is realizable in string theory, and give examples involving orientifold compactifications of IIB string theory a ..."

The large N limit of superconformal field theories and supergravity
, 1998
"... We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of AntideSitter spacetimes, spheres and other compact manifolds. This is shown by taking some branes in the full M/string theory and ..."

in the superconformal group (as opposed to just the superPoincare group). The ’t Hooft limit of 3+1 N = 4 superYangMills at the conformal point is shown to contain strings: they are IIB strings. We conjecture that compactifications of M/string theory on various AntideSitter spacetimes is dual to various conformal

Moduli Stabilization from Fluxes in a Simple IIB Orientifold
, 2002
"... We study novel type IIB compactifications on the T 6 /Z2 orientifold. This geometry arises in the Tdual description of Type I theory on T 6, and one normally introduces 16 spacefilling D3branes to cancel the RR tadpoles. Here, we cancel the RR tadpoles either partially or fully by turning on thre ..."

Compactifications of Type IIB Strings to Four Dimensions with Nontrivial Classical Potential
, 1996
"... Type IIB strings are compactified on a CalabiYau threefold. When CalabiYauvalued expectation values are given to the NSNS and RR threeform field strengths, the dilaton hypermultiplet becomes both electrically and magnetically charged. The resultant classical potential is calculated, and minima ..."

Nongeometric Flux Compactifications
, 2006
"... We investigate a simple class of type II string compactifications which incorporate nongeometric “fluxes” in addition to “geometric flux” and the usual Hfield and RR fluxes. These compactifications are nongeometric analogues of the twisted torus. We develop Tduality rules for NSNS geometric and ..."

Heterotic flux compactifications and their moduli
, 2006
"... We study supersymmetric compactification to four dimensions with nonzero Hflux in heterotic string theory. The background metric is generically conformally balanced and can be conformally Kähler if the primitive part of the Hflux vanishes. Analyzing the linearized variational equations, we write ..."

We systematically analyse globally consistent SU(5) GUT models on intersecting D7branes in genuine CalabiYau orientifolds with O3 and O7planes. Beyond the wellknown tadpole and Ktheory cancellation conditions there exist a number of additional subtle but quite restrictive constraints. For the realisation of SU(5) GUTs with gauge symmetry breaking via U(1)Y flux we present two classes of suitable CalabiYau manifolds defined via del Pezzo transitions of the elliptically fibred hypersurface P1,1,1,6,9[18] and of the Quintic P1,1,1,1,1[5], respectively. To define an orientifold projection we classify all involutions on del Pezzo surfaces. We work out the model building prospects of these geometries and present five globally consistent string GUT models in detail, including a 3generation SU(5) model with no exotics whatsoever. We also realise other phenomenological features such as the 10105H Yukawa coupling and comment on the possibility of moduli stabilisation, where we find an entire new set of socalled swisscheese type CalabiYau manifolds. It is
