Cosmological perturbations and dynamical analysis for interacting quintessence
read the original abstract
We present the dynamical analysis for interacting quintessence, considering linear cosmological perturbations. Matter perturbations improve the background analysis and viable critical points describing the transition of the three cosmological eras are found. The stability of those fixed points are similar to previous studies in the literature, for both coupled and uncoupled cases, leading to a late-time attractor.

A microphysically inspired approach to dark matter-dark energy interactions: first bounds on dark-sector scattering cross sections
A microphysically motivated Q∝ρ² dark-sector interaction is constrained by cosmological data, giving upper limits A<7.6×10⁻²⁵, B<0.048, and H₀=67.71±0.65 km/s/Mpc.
