On the K-point in moduli space
Jarod Hattab, Eran Palti, Joan Quirant
We study a class of infinite-distance loci, referred to as K-points, in one-parameter complex-structure moduli spaces of type IIB string theory compactified on Calabi-Yau manifolds…
On the limitations of non-geometric fluxes to realize dS vacua
David Prieto, Joan Quirant, Pramod Shukla
In this paper, we perform a systematic and analytical exploration of de Sitter conditions in type IIA compactifications with (non-)geometric fluxes along with the standard NS-NS an…
Regge growth of isolated massive spin-2 particles and the Swampland
Suman Kundu, Eran Palti, Joan Quirant
We consider an effective theory with a single massive spin-2 particle and a gap to the cutoff. We couple the spin-2 particle to gravity, and to other lower-spin fields, and study t…
Aspects of type IIA AdS orientifold vacua
Joan Quirant
In this thesis we explore the vacua structure of type IIA orientifold (CY) compactifications with fluxes, from the 4d and the 10d point of view. We start by reviewing type IIA Cala…
New instabilities for non-supersymmetric AdS orientifold vacua
Fernando Marchesano, Joan Quirant, Matteo Zatti
We consider massive type IIA orientifold compactifications of the form AdS, where admits a Calabi-Yau metric and is threaded by background fluxes. From a 4d vi…
Non-integer conformal dimensions for type IIA flux vacua
Joan Quirant
We study the conformal dimensions of the would-be dual operators to the stabilized moduli for two non-supersymmetric DGKT vacua. For the first of them, related to the standard SUSY…
BIonic membranes and AdS instabilities
Fernando Marchesano, David Prieto, Joan Quirant
We study 4d membranes in type IIA flux compactifications of the form AdS, where admits a Calabi--Yau metric. These models feature scale separation and D6-brane…
Systematics of Type IIA moduli stabilisation
Fernando Marchesano, David Prieto, Joan Quirant +1
We analyse the flux-induced scalar potential for type IIA orientifolds in the presence of -form, geometric and non-geometric fluxes. Just like in the Calabi-Yau case, the potent…
On supersymmetric AdS orientifold vacua
Fernando Marchesano, Eran Palti, Joan Quirant +1
In this work we study ten-dimensional solutions to type IIA string theory of the form AdS x which contain orientifold planes and preserve N=1 supersymmetry. In particular…
A Landscape of AdS Flux Vacua
Fernando Marchesano, Joan Quirant
We analyse type IIA Calabi-Yau orientifolds with background fluxes and D6-branes. Rewriting the F-term scalar potential as a bilinear in flux-axion polynomials yields a more effici…
