We use reinforcement learning as a means of constructing string compactifications with
prescribed properties. Specifically, we study heterotic GUT models on Calabi‐Yau three …

The string theory landscape may include a multitude of ultraviolet embeddings of the
Standard Model, but identifying these has proven difficult due to the enormous number of …

A bstract We study F-theory compactifications to four dimensions that exhibit discrete gauge
symmetries. Geometrically these arise by deforming elliptic fibrations with two sections to a …

We derive an approximate analytic relation between the number of consistent heterotic
Calabi-Yau compactifications of string theory with the exact charged matter content of the …

We present closed form expressions for the ranks of all cohomology groups of holomorphic
line bundles on several Calabi‐Yau threefolds realised as complete intersections in …

The goal of identifying the Standard Model of particle physics and its extensions within string
theory has been one of the principal driving forces in string phenomenology. Recently, the …

A bstract We develop techniques, based on differential geometry, to compute holomorphic
Yukawa couplings for heterotic line bundle models on Calabi-Yau manifolds defined as …

We present a numerical algorithm for computing the spectrum of the Laplace-de Rham
operator on Calabi-Yau manifolds, extending previous work on the scalar Laplace operator …

A bstract We present a general method for computing Hodge numbers for Calabi-Yau
manifolds realised as discrete quotients of complete intersections in products of projective …

We study heterotic Calabi-Yau models with hypercharge flux breaking, where the visible E 8
gauge group is directly broken to the standard model group by a nonflat gauge bundle …
