Neural Network Field Theories: Non-Gaussianity, Actions, and Locality
Mehmet Demirtas, James Halverson, Anindita Maiti +2
Both the path integral measure in field theory and ensembles of neural networks describe distributions over functions. When the central limit theorem can be applied in the infinite…
Computational Mirror Symmetry
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We present an efficient algorithm for computing the prepotential in compactifications of type II string theory on mirror pairs of Calabi-Yau threefolds in toric varieties. Applying…
CYTools: A Software Package for Analyzing Calabi-Yau Manifolds
Mehmet Demirtas, Andres Rios-Tascon, Liam McAllister
We provide a user's guide to version 1.0 of the software package CYTools, which we designed to compute the topological data of Calabi-Yau hypersurfaces in toric varieties. CYTools…
PQ Axiverse
Mehmet Demirtas, Naomi Gendler, Cody Long +2
We show that the strong CP problem is solved in a large class of compactifications of string theory. The Peccei-Quinn mechanism solves the strong CP problem if the CP-breaking effe…
A Cosmological Constant That is Too Small
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct a vacuum of string theory in which the magnitude of the vacuum energy is in Planck units. Regrettably, the sign of the vacuum energy is negative, and som…
Small Cosmological Constants in String Theory
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct supersymmetric vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orie…
Superradiance in String Theory
Viraf M. Mehta, Mehmet Demirtas, Cody Long +3
We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance exclud…
Superradiance Exclusions in the Landscape of Type IIB String Theory
Viraf M. Mehta, Mehmet Demirtas, Cody Long +3
We obtain constraints from black hole superradiance in an ensemble of compactifications of type IIB string theory. The constraints require knowing only the axion masses and self-in…
Conifold Vacua with Small Flux Superpotential
Mehmet Demirtas, Manki Kim, Liam McAllister +1
We introduce a method for finding flux vacua of type IIB string theory in which the flux superpotential is exponentially small and at the same time one or more complex structure mo…
Bounding the Kreuzer-Skarke Landscape
Mehmet Demirtas, Liam McAllister, Andres Rios-Tascon
We study Calabi-Yau threefolds with large Hodge numbers by constructing and counting triangulations of reflexive polytopes. By counting points in the associated secondary polytopes…
Vacua with Small Flux Superpotential
Mehmet Demirtas, Manki Kim, Liam McAllister +1
We describe a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small. We present an example with $W_0 \approx…
Minimal Surfaces and Weak Gravity
Mehmet Demirtas, Cody Long, Liam McAllister +1
We show that the Weak Gravity Conjecture (WGC) implies a nontrivial upper bound on the volumes of the minimal-volume cycles in certain homology classes that admit no calibrated rep…
The Kreuzer-Skarke Axiverse
Mehmet Demirtas, Cody Long, Liam McAllister +1
We study the topological properties of Calabi-Yau threefold hypersurfaces at large . We obtain two million threefolds by triangulating polytopes from the Kreuzer-Skark…
Lower-Critical Spin-Glass Dimension from 23 Sequenced Hierarchical Models
Mehmet Demirtas, Asli Tuncer, A. Nihat Berker
The lower-critical dimension for the existence of the Ising spin-glass phase is calculated, numerically exactly, as for a family of hierarchical lattices, from an ess…
