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…
