| contents | <p>We propose a cosmological model in which dark energy (DE) and dark matter (DM) interact in<br>the early Universe through an energy transfer mechanism that dynamically weakens as the<br>Universe expands. This interaction naturally leads to a self-regulating regime in which the<br>energy densities of DE and DM remain comparable for an extended period, thereby addressing<br>the coincidence problem. As the interaction term decays, dark energy effectively decouples and<br>begins to dominate, triggering late-time cosmic acceleration. The model preserves the successes<br>of ΛCDMatlate times while allowing for modified expansion history at earlier epochs,<br>potentially alleviating the H₀ tension. We outline the theoretical framework, discuss<br>phenomenological implications, and propose a connection to an information-based description of<br>cosmological dynamics.<br>This work presents a new theoretical framework. Numerical validation using CLASS is planned<br>in future updates</p> |
