Calculating Axion-Matter Couplings in String Theory
Joshua N. Benabou, Naomi Gendler, Thomas R. Harvey +1
In this work we calculate, for the first time, the dominant perturbative contributions to axion--matter couplings explicitly in string theory. Concretely, we compute these coupling…
Catastrophic Inflation in the Axiverse
Naomi Gendler, Oliver Janssen, Matthew Kleban +1
In the landscape of compactifications of type IIB string theory on O3/O7 orientifolds of Calabi--Yau threefolds, we identify regions of the axion potential in specific geometries t…
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…
Universality in the Axiverse
Junyi Cheng, Naomi Gendler
Studies of axion effective theories in the type IIB Calabi-Yau landscape have revealed that hierarchies in cycle volumes drive correlations between axion physics and the number of…
Constraining the axiverse with reionization
Ziwen Yin, Hanyu Cheng, Eleonora Di Valentino +3
Axions that couple to electromagnetism are produced in the early Universe by, among other channels, freeze-in via the Primakoff process. For sufficiently large axion masses, the sa…
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.…
QCD Axion Dark Matter in String Theory: Haloscopes and Helioscopes as Probes of the Landscape
Naomi Gendler, David J. E. Marsh
Laboratory experiments have the capacity to detect the QCD axion in the next decade, and precisely measure its mass, if it composes the majority of the dark matter. In type IIB str…
Axions in the Dark Dimension
Naomi Gendler, Cumrun Vafa
The dark dimension scenario, which is motivated from Swampland principles and predicts a single micron scale extra dimension, suggests a consistent framework for the dark sector of…
Counting Calabi-Yau Threefolds
Naomi Gendler, Nate MacFadden, Liam McAllister +4
We enumerate topologically-inequivalent compact Calabi-Yau threefold hypersurfaces. By computing arithmetic and algebraic invariants and the Gopakumar-Vafa invariants of curves, we…
Axion minima in string theory
Naomi Gendler, Oliver Janssen, Matthew Kleban +2
We study the landscape of axion theories in compactifications of type IIB string theory on orientifolds of Calabi-Yau threefolds. In a sample of approximately 400,000 geometries we…
Glimmers from the Axiverse
Naomi Gendler, David J. E. Marsh, Liam McAllister +1
We study axion-photon couplings in compactifications of type IIB string theory. We find that these couplings are systematically suppressed compared to the inverse axion periodicity…
Moduli Space Reconstruction and Weak Gravity
Naomi Gendler, Ben Heidenreich, Liam McAllister +2
We present a method to construct the extended Kähler cone of any Calabi-Yau threefold by using Gopakumar-Vafa invariants to identify all geometric phases that are related by flops…
Superpotentials from Singular Divisors
Naomi Gendler, Manki Kim, Liam McAllister +2
We study Euclidean D3-branes wrapping divisors in Calabi-Yau orientifold compactifications of type IIB string theory. Witten's counting of fermion zero modes in terms of the co…
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…
Merging the Weak Gravity and Distance Conjectures Using BPS Extremal Black Holes
Naomi Gendler, Irene Valenzuela
We analyze the charge-to-mass structure of BPS states in general infinite-distance limits of compactifications of Type IIB string theory on Calabi-Yau three-folds,…
