The Hodge Numbers of Divisors of Calabi-Yau Threefold Hypersurfaces
Andreas P. Braun, Cody Long, Liam McAllister +2
We prove a formula for the Hodge numbers of square-free divisors of Calabi-Yau threefold hypersurfaces in toric varieties. Euclidean branes wrapping divisors affect the vacuum stru…
Vacuum Selection from Cosmology on Networks of String Geometries
Jonathan Carifio, William J. Cunningham, James Halverson +3
We introduce network science as a framework for studying the string landscape. Two large networks of string geometries are constructed, where nodes are extra-dimensional six-manifo…
On the Scarcity of Weak Coupling in the String Landscape
James Halverson, Cody Long, Benjamin Sung
We study the geometric requirements on a threefold base for the corresponding F-theory compactification to admit a weakly-coupled type IIB limit. We examine both the standard Sen l…
On Algorithmic Universality in F-theory Compactifications
James Halverson, Cody Long, Benjamin Sung
We study universality of geometric gauge sectors in the string landscape in the context of F-theory compactifications. A finite time construction algorithm is presented for $\frac4…
An Ultralight Axion in Supersymmetry and Strings and Cosmology at Small Scales
James Halverson, Cody Long, Pran Nath
Dynamical mechanisms to generate an ultralight axion of mass eV in supergravity and strings are discussed. An ultralight particle of this mass provides a c…
