Racetrack potentials and the de Sitter swampland conjectures
(Springer, 2019-01)
We show that one can find de Sitter critical points (saddle points) in models of flux compactification of Type IIB String Theory without any uplifting terms and in the presence of several moduli. We demonstrate this by ...
Universal class of type-IIB flux vacua with analytic mass spectrum
(American Physical Society, 2021-05)
We report on a new class of flux vacua generically present in Calabi-Yau compactifications of type-IIB string theory. At these vacua, the mass spectrum of the complete axiodilaton/complex structure sector is given, to ...
Towards a Complete Mass Spectrum of Type-IIB Flux Vacua at Large Complex Structure
(Springer, 2021-04-15)
The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible. A common strategy to solve this problem is to consider ...
Analytics of type IIB flux vacua and their mass spectra
(Springer, 2023-01)
We analyze the tree-level potential of type IIB flux compactifications in warped Calabi-Yau orientifolds, in regions of weak coupling and moderately large complex structure. In this regime, one may approximate the flux-induced ...
Slepian models for Gaussian random landscapes
(Springer, 2020-05-27)
Phenomenologically interesting scalar potentials are highly atypical in generic random landscapes. We develop the mathematical techniques to generate constrained random potentials, i.e.Slepian models, which can globally ...
Brane nucleation in supersymmetric models
(Springer Nature, 2023-10-11)
This paper explores the process of vacuum decay in supersymmetric models related to flux compactifications. In particular, we describe these instabilities within supersymmetric Lagrangians for a single three-form multiplet. ...
Symmetric fluxes and small tadpoles
(Springer Nature, 2023-08-04)
The analysis of type IIB flux vacua on warped Calabi-Yau orientifolds becomes considerably involved for a large number of complex structure fields. We however show that, for a quadratic flux superpotential, one can devise ...
