Moduli space holography and the finiteness of flux vacua
Journal of High Energy Physics, 2021 A holographic perspective to study and characterize field spaces that arise in string compactifications is suggested. A concrete correspondence is developed by studying two-dimensional moduli spaces in supersymmetric string compactifications.

New non-supersymmetric flux vacua in string theory
Journal of High Energy Physics, 2023 In this note we construct large ensembles of supersymmetry breaking solutions arising in the context of flux compactifications of type IIB string theory.

M-theory Compactifications to Three Dimensions with M2-brane Potentials [PDF]
, 2013 We study a class of compactifications of M-theory to three dimensions that preserve N=2 supersymmetry and which have the defining feature that a probe space-time filling M2 brane feels a non-trivial potential on the internal manifold.

Type IIB flux compactifications with h 1,1 = 0
Journal of High Energy Physics, 2022 We revisit flux compactifications of type IIB string theory on ‘spaces’ dual to rigid Calabi-Yau manifolds. This rather unexplored part of the string landscapes harbors many interesting four-dimensional solutions, namely supersymmetric N $$ \mathcal{N} $$

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.

Three-forms in supergravity and flux compactifications
European Physical Journal C: Particles and Fields, 2017 We present a duality procedure that relates conventional four-dimensional matter-coupled $$\mathcal{N}=1$$ N = 1 supergravities to dual formulations in which auxiliary fields are replaced by field strengths of gauge three-forms.

Sharpening the boundaries between flux landscape and swampland by tadpole charge
Journal of High Energy Physics, 2021 We investigate the vacuum structure of four-dimensional effective theory arising from Type IIB flux compactifications on a mirror of the rigid Calabi-Yau threefold, corresponding to a T-dual of the DeWolfe-Giryavets-Kachru-Taylor model in Type IIA flux ...

Twisted tori and fluxes: a no go theorem for Lie groups of weak G_2 holonomy [PDF]
Nucl.Phys. B751 (2006) 343-375, 2006 In this paper we prove the theorem that there exists no 7--dimensional Lie group manifold G of weak G2 holonomy. We actually prove a stronger statement, namely that there exists no 7--dimensional Lie group with negative definite Ricci tensor Ric_{IJ}.

Fluxes in exceptional field theory and threebrane sigma-models
Journal of High Energy Physics, 2019 Starting from a higher Courant bracket associated to exceptional generalized geometry, we provide a systematic derivation of all types of fluxes and their Bianchi identities for four-dimensional compactifications of M-theory.
