Non-invertible symmetries in the axiverse, and the imaginary wormholes
Daniele Licciardello, Luca Martucci
We study the symmetry structure of four-dimensional axiverse effective field theories with multiple axions coupled to abelian gauge sectors, including their extensions to broad cla…

Extending the Dynamical Systems Toolkit: Coupled Fields in Multiscalar Dark Energy
Daniele Licciardello, Saba Rahimy, Ivonne Zavala
We study the dynamics of a two-field scalar model consisting of an axion-saxion pair with both kinetic and potential couplings, as motivated by string theory compactifications. We…
