The Dark Dimension meets the Axiverse
Kevin Langhoff, Maria Ramos, Mario Reig
We explore the cosmological implications of combining dark dimension scenarios with an axiverse. If gauge sectors are realized on branes, towers of Kaluza-Klein (KK) excitations of…
Axion couplings in Orbifold GUTs
Prateek Agrawal, Michael Nee, Mario Reig
We consider the coupling of axions to gauge bosons in higher-dimensional Grand Unified Theories (GUT) inspired by string theory constructions with D-branes on orbifold singularitie…
Axion Quality Problem: Keep Calm and Baryon
Prateek Agrawal, Anson Hook, Vazha Loladze +1
Axion models generically suffer from a severe quality problem when coupled to gravity. In this article we provide a very simple model with a high quality axion. The axion is a pseu…
Supercooled Confinement
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
We study general properties of confinement phase transitions in the early universe. An observable gravitational wave signal from such transitions requires significant supercooling.…
Higher Axion Strings
Vazha Loladze, Arthur Platschorre, Mario Reig
We study the minimal requirements to obtain axion strings for axions with exponentially good quality. These ingredients appear in theories where an axion coming from a higher-form…
Axion Couplings in Heterotic String Theory
Prateek Agrawal, Michael Nee, Mario Reig
We study the coupling of axions to gauge bosons in heterotic string theory. The axion-gauge boson couplings in the low energy 4d theory are derived by matching mixed anomalies betw…
Searching for axion forces with spin precession in atoms and molecules
Prateek Agrawal, Nicholas R. Hutzler, David E. Kaplan +2
We propose to use atoms and molecules as quantum sensors of axion-mediated monopole-dipole forces. We show that electron spin precession experiments using atomic and molecular beam…
