-fibrations in F-theory and String Dualities
Lara B. Anderson, James Gray, Mohsen Karkheiran +2
In this work we study F-theory compactifications on elliptically fibered Calabi-Yau n-folds which have -fibered base manifolds. Such geometries, which we study in bot…
Automatic Enhancement in 6D Supergravity and F-theory Models
Nikhil Raghuram, Washington Taylor, Andrew P. Turner
We observe that in many F-theory models, tuning a specific gauge group and matter content under certain circumstances leads to an automatic enhancement to a larger gauge gr…
Moduli-dependent Calabi-Yau and SU(3)-structure metrics from Machine Learning
Lara B. Anderson, Mathis Gerdes, James Gray +3
We use machine learning to approximate Calabi-Yau and SU(3)-structure metrics, including for the first time complex structure moduli dependence. Our new methods furthermore improve…
General F-theory models with tuned symmetry
Nikhil Raghuram, Washington Taylor, Andrew P. Turner
We construct a general form for an F-theory Weierstrass model over a general base giving a 6D or 4D supergravity theory with gauge group $(\operatorname{SU}(3) \times \operatorname…
Large U(1) charges in F-theory
Nikhil Raghuram, Washington Taylor
We show that massless fields with large abelian charges (up to at least q = 21) can be constructed in 6D F-theory models with a U(1) gauge group. To show this, we explicitly constr…
Exotic matter on singular divisors in F-theory
Denis Klevers, David R. Morrison, Nikhil Raghuram +1
We analyze exotic matter representations that arise on singular seven-brane configurations in F-theory. We develop a general framework for analyzing such representations, and work…
