The DNA of Calabi-Yau Hypersurfaces
Nate MacFadden, Andreas Schachner, Elijah Sheridan
We implement Genetic Algorithms for triangulations of four-dimensional reflexive polytopes which induce Calabi-Yau threefold hypersurfaces via Batyrev's construction. We demonstrat…
Calabi-Yau Threefolds from Vex Triangulations
Nate MacFadden, Elijah Sheridan
We study the birational geometry (i.e., Kähler moduli space) of Calabi--Yau (CY) threefold hypersurfaces in toric varieties arising from four-dimensional reflexive polytopes. In pa…
Holes in Calabi-Yau Effective Cones
Naomi Gendler, Elijah Sheridan, Michael Stillman +1
Motivated by their role in non-perturbative potentials in string theory, we study divisors in effective cones of Calabi-Yau threefolds. We give examples of geometries for which som…
Bayesian inference on Calabi--Yau moduli spaces and the axiverse: experimental data meets string theory
Mudit Jain, Elijah Sheridan, David J. E. Marsh +3
We develop tools of Bayesian inference on the moduli space of Calabi--Yau (CY) manifolds. We sample from the invariant Weil--Petersson (WP) measure using Markov Chain Monte Carlo a…
Fuzzy Axions and Associated Relics
Elijah Sheridan, Federico Carta, Naomi Gendler +6
We study fuzzy axion dark matter in type IIB string theory, for axions descending from the Ramond-Ramond four-form in compactifications on orientifolds of Calabi-Yau hypersurfaces.…
