The cosmological dynamics of minimally coupled scalar field that couple to the background matter with thermal interactions is investigated in exponential potential. The conditions for the existence and stability of various critical points as well as their cosmological implications are obtained. Although we show that the effects of thermal interaction such as depressing the equation-of-state parameter of quintessence, is only important at the early time, the evolution of equation-of-state parameter of quintessence is manifested. The upper bound is required on the coupling between quintessence and relativistic relic particles such as photons and neutrinos.

    Accelerating scaling attractors where DM and barotropic fluid coexist at late times arise only for DM-density-controlled interactions with energy transfer from DM.

  2. Accelerating scaling solutions from dark matter particle creation

    gr-qc 2026-04 conditional novelty 5.0 of 10

    Accelerating scaling attractors without dark energy appear only when the interaction is controlled by DM density and energy flows from DM to a barotropic fluid.
