A comprehensive dynamical and phenomenological analysis of structure growth in curvature-modulated coupled quintessence scenario

Anirban Chatterjee, Yungui Gong

We investigate an interacting dark energy-dark matter model within the quintessence framework, characterized by the coupling term $Q_0=\alpha \kappa {\rho }_m\dot{\varphi }\left[1-\beta R/(6H^2)\right]$, a…
