Journal of High Energy Physics, 2021 We consider, at the linearized level, the superspace formulation of lower-dimensional F-theory. In particular, we describe the embedding of 3D Type II super-gravity of the superstring, or 4D, N = 1 supergravity of M-theory, into the corresponding F ...

Journal of High Energy Physics, 2017 We construct supersymmetric AdS3 solutions in F-theory, that is Type IIB supergravity with varying axio-dilaton, which are holographically dual to 2d N = 0 4 $$ \mathcal{N}=\left(0,4\right) $$ superconformal field theories with small superconformal ...

The frozen phase of F-theory [PDF]
Journal of High Energy Physics, 2018 We study the interpretation of O7+-planes in F-theory, mainly in the context of the six-dimensional models. In particular, we study how to assign gauge algebras and matter content to seven-branes and their intersections, and the implication of anomaly ...

The gravitational sector of 2d (0, 2) F-theory vacua [PDF]
Journal of High Energy Physics, 2017 F-theory compactifications on Calabi-Yau fivefolds give rise to two-dimensional N = (0, 2) supersymmetric field theories coupled to gravity. We explore the dilaton supergravity defined by the moduli sector of such compactifications.

General U(1)×U(1) F-theory compactifications and beyond: geometry of unHiggsings and novel matter structure [PDF]
, 2015 A bstractWe construct the general form of an F-theory compactification with two U(1) factors based on a general elliptically fibered Calabi-Yau manifold with Mordell-Weil group of rank two.

F-theory flux vacua at large complex structure [PDF]
Journal of High Energy Physics, 2021 We compute the flux-induced F-term potential in 4d F-theory compactifications at large complex structure. In this regime, each complex structure field splits as an axionic field plus its saxionic partner, and the classical F-term potential takes the form

Generalized Symmetries in F-theory and the Topology of Elliptic Fibrations [PDF]
SciPost Physics, 2022 We realize higher-form symmetries in F-theory compactifications on non-compact elliptically fibered Calabi-Yau manifolds. Central to this endeavour is the topology of the boundary of the non-compact elliptic fibration, as well as the explicit ...

Higher-form symmetries and their anomalies in M-/F-theory duality [PDF]
Physical Review D, 2021 We explore higher-form symmetries of M- and F-theory compactified on elliptic fibrations, determined by the topology of their asymptotic boundaries. The underlying geometric structures are shown to be equivalent to known characterizations of the gauge ...

Quadrillion F-Theory Compactifications with the Exact Chiral Spectrum of the Standard Model. [PDF]
Physical Review Letters, 2019 We present O(10^{15}) string compactifications with the exact chiral spectrum of the standard model of particle physics. This ensemble of globally consistent F-theory compactifications automatically realizes gauge coupling unification.

Perturbative moduli stabilisation in type IIB/F-theory framework [PDF]
The European Physical Journal C, 2018 We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi–Yau manifolds, in the presence of 7-branes, that does not rely on non-perturbative effects.
