Scaling limits of dS vacua and the swampland
Journal of High Energy Physics, 2019 We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling.

New de Sitter solutions of 10d type IIB supergravity
Journal of High Energy Physics, 2020 We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D 5-branes and orientifold O 5-planes, as well as a new Minkowski one.

Systematics of type IIB moduli stabilisation with odd axions
Journal of High Energy Physics, 2022 Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua.

The tadpole conjecture at large complex-structure
Journal of High Energy Physics, 2022 The tadpole conjecture by Bena, Blåbäck, Graña and Lüst effectively states that for string-theory compactifications with a large number of complex-structure moduli, not all of these moduli can be stabilized by fluxes.

Branes with brains: exploring string vacua with deep reinforcement learning
Journal of High Energy Physics, 2019 We propose deep reinforcement learning as a model-free method for exploring the landscape of string vacua. As a concrete application, we utilize an artificial intelligence agent known as an asynchronous advantage actor-critic to explore type IIA ...

De Sitter vacua — when are ‘subleading corrections’ really subleading?
Journal of High Energy Physics, 2023 We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the context of strongly-warped LVS de Sitter vacua, that it is impossible to ...

, 2007 15 pagesWe argue that tachyon-free type I string vacua with supersymmetry breaking in the open sector at the string scale can be interpreted, via S and T-duality arguments, as metastable vacua of supersymmetric type I superstring.

On fluxes in the 19 Landau-Ginzburg model
Journal of High Energy Physics, 2023 In this paper we present a large class of flux backgrounds and solve the shortest vector problem in type IIB string theory on an orientifold of the 19 Landau-Ginzburg model.

De-Sitter vacua via consistent D terms [PDF]
, 2005 We introduce a new mechanism for producing locally stable de-Sitter or Minkowski vacua, with spontaneously broken N=1 supersymmetry and no massless scalars, applicable to superstring and M-theory compactifications with fluxes. We illustrate the mechanism
