Gravitational Axiverse Spectroscopy: Seeing the Forest for the Axions
Ema Dimastrogiovanni, Matteo Fasiello, Jacob M. Leedom +2
We consider inflationary models with multiple spectator axions coupled to dark gauge sectors via Chern-Simons (CS) terms. The energy injection into Abelian gauge fields from the ax…
Generalized Narain Theories Decoded: Discussions on Eisenstein series, Characteristics, Orbifolds, Discriminants and Ensembles in any Dimension
Meer Ashwinkumar, Abhiram Kidambi, Jacob M. Leedom +1
We study a class of newly-introduced CFTs associated with even quadratic forms of general signature, which we call generalized Narain theories. We first summarize the properties of…
Implications of Protecting the QCD Axion in the Dual Description
Gongjun Choi, Jacob Leedom
The QCD axion can be be formulated in a dual description as a massive 2-form field. In this picture, the QCD axion quality problem translates into the question if there are additio…
Duality Origami: Emergent Ensemble Symmetries in Holography and Swampland
Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki
We discuss the interrelations between several ideas in quantum gravity -- holography, the Swampland, and the concept of ensemble averaging. To do so, we study ensemble averages of…
