Uplifts of maximal supergravities and transitions to non-geometric vacua
Journal of High Energy Physics, 2019 We describe a new procedure to obtain consistent backgrounds that uplift vacua and deformations of various maximal gauged supergravities by taking a known solution and performing singular limits along the moduli space of the corresponding 4-dimensional ...

Dual Gauged Supergravities [PDF]
, 2007 We shall review a novel formulation of four dimensional gauged supergravity which is manifestly covariant with respect to the non-perturbative electric-magnetic duality symmetry transformations of the ungauged theory, at the level of the equations of ...

Generalised Penrose Limits and PP-Waves
, 2004 In this paper we construct generalised Penrose limits for the solutions of massive type IIA supergravity. We consider a Freund-Rubin type solution and apply these {\it massive} Penrose limits and obtain supersymmetric pp-wave which is a standard type IIA

Partition Functions, Duality, and the Tube Metric [PDF]
, 1997 The partition function of type IIA and B strings on R^6xK3, in the T^4/Z_2 orbifold limit, is explicitly computed as a modular invariant sum over spin strutures required by perturbative unitarity in order to extend the analysis to include type II strings

Branes in Anti de Sitter Space-Time [PDF]
, 1998 An intense study of the relationship between certain quantum theories of gravity realized on curved backgrounds and suitable gauge theories, has been originated by a remarkable conjecture put forward by Maldacena almost one year ago.

Type I Vacua from Diagonal $Z_3$-Orbifolds [PDF]
, 1999 We discuss the open descendants of diagonal irrational $Z_3$ orbifolds, starting from the $c=2$ case and analyzing six-dimensional and four-dimensional models.

Journal of High Energy Physics, 2020 We study the topological properties of Calabi-Yau threefold hypersurfaces at large h 1,1. We obtain two million threefolds X by triangulating polytopes from the Kreuzer-Skarke list, including all polytopes with 240 ≤ h 1,1 ≤ 491.

Black Holes, Branes and Superconformal Symmetry
, 1999 The main focus of this lecture is on extended objects in adS*S bosonic backgrounds with unbroken supersymmetry. The backgrounds are argued to be exact, special consideration are given to the non-maximal supersymmetry case.

From Minkowski to de Sitter in multifield no-scale models
Journal of High Energy Physics, 2019 We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these single-field Minkowski superpotentials.

Large field ranges from aligned and misaligned winding
Journal of High Energy Physics, 2019 We search for effective axions with super-Planckian decay constants in type IIB string models. We argue that such axions can be realised as long winding trajectories in complex-structure moduli space by an appropriate flux choice.
