Multifield Dark Energy Dynamics

This repository contains Python scripts to reproduce background‐dynamics plots (Figures 4, 5 and 10) from “Cosmological dynamics of multifield dark energy” (Akrami et al.).

Specifically:

• Figures 4 & 5: Trajectories in the ((w_\phi,,\Omega_\phi)) phase space for two classes of field‑space metrics (power‑law and hyperbolic).
• Figure 10: The Swampland ratio (\lvert\nabla V\rvert/V) as a function of the radial field (r) (and (\alpha,\theta)).

All scripts save their plots as PNGs.
