Flat F-theory and friends
We discuss F-theory backgrounds associated to flat torus bundles over Ricci-flat manifolds. In this setting the F-theory background can be understood...

Twisted Fibrations in M/F-theory
In this work we investigate 5-dimensional theories obtained from M-theory on genus one fibered threefolds which exhibit twisted algebras in their...

𝒩 = 1 SCFTs from F-theory on Orbifolds
We study four-dimensional superconformal field theories living on the worldvolume of D 3 branes probing minimally-supersymmetric F-theory backgrounds,...

Chiral Matter Multiplicities and Resolution-Independent Structure in 4D F-Theory Models
Motivated by questions related to the landscape of flux compactifications, we combine new and existing techniques into a systematic, streamlined...

A viable form of teleparallel F(T) theory of gravity
Unlike F ( R ) gravity, pure F ( T ) gravity in the vacuum dominated era does not produce any form, viable to study cosmological evolution. Factually, it...

Large U(1) charges from flux breaking in 4D F-theory models
We study the massless charged spectrum of U(1) gauge fields in F-theory that arise from flux breaking of a nonabelian group. The U(1) charges that...

D-brane and F-theory Model Building
We review recent progress in the construction of four-dimensional vacua of Type II string theory and F-theory which yield the Standard Model of...

Towards natural and realistic E7 GUTs in F-theory
We consider phenomenological aspects of a natural class of Standard Model-like supersymmetric F-theory vacua realized through flux breaking of rigid E

Perturbative F-theory 10-brane and M-theory 5-brane
The exceptional symmetry is realized perturbatively in F-theory which is the manifest U-duality theory. The SO(5) U-duality symmetry acts on both the...

F-theory on 6D symmetric toroidal orbifolds
In this work we study F-theory on symmetric toroidal orbifolds that exhibit roto-translations, which are point group rotations accompanied by...

Scalar field in unimodular f(R, T) theory
In this paper, we are fundamentally interested in minimally coupled scalar field as source of unimodular Friedmann–Robertson–Walker (FRW) spacetime....

Gauge symmetry breaking with fluxes and natural Standard Model structure from exceptional GUTs in F-theory
We give a general description of gauge symmetry breaking using vertical and remainder fluxes in 4D F-theory models. The fluxes can break a geometric...

Spherically symmetric generating solutions in f(R) theory
The main objective of this work, is to develop a novel general framework for generating solutions of stellar models in f ( R ) theory of gravity with...

Phase-space analysis of a novel cosmological model in f(Q) theory
The vanishing affine connections have been used solely while adopting the modified f ( Q ) gravity theory to the cosmology. Consequently, researchers...

Orders of vanishing and U(1) charges in F-theory
Many interesting questions about F-theory models, including several concerning the F-theory swampland, involve massless matter charged under U(1)...

Non-split singularities and conifold transitions in F-theory
In F-theory, if a fiber type of an elliptic fibration involves a condition that requires an exceptional curve to split into two irreducible...

The discrete Green-Schwarz mechanism in 6D F-theory and elliptic genera of non-critical strings
We study global anomalies of discrete gauge symmetries in six-dimensional supergravities and their realizations in F-theory. We explicitly construct...

Small-instanton transitions in F-theory
We study the phase transition between G -instantons and D3-branes quantitatively. A G -instanton is a classical solution to the self-dual equation of...
