Clockwork axions in cosmology. Is chromonatural inflation chrononatural? by Prateek Agrawal, JiJi Fan, Matthew Reece

“…Abstract Many cosmological models rely on large couplings of axions to gauge fields. Examples include theories of magnetogenesis, inflation on a steep potential, chiral gravitational waves, and chromonatural inflation. …”

Axion monodromy inflation, trapping mechanisms and the swampland by Weijie Jin, Robert Brandenberger, Lavinia Heisenberg

“…Abstract We study the effects of particle production on the evolution of the inflaton field in an axion monodromy model with the goal of discovering in which situations the resulting dynamics will be consistent with the swampland constraints. …”

Brane-Antibrane Backreaction in Axion Monodromy Inflation by Conlon, J

“…We show that logarithmic backreaction is generic for 5-branes wrapping distant but homologous 2-cycles, and we argue that this destabilises models of axion monodromy inflation involving NS5 brane-antibrane pairs in separate warped throats towards an uncontrolled region.…”
