A Dissipative Conformal-Maintenance Power as a Candidate Sourceof Dark Energy Implications for the Cosmological-Constant Coincidence and Hubble-Tension Problems

Modern standard cosmology (ΛCDM) faces three profound theoretical and observational crises: the cosmological constant problem, the cosmic coincidence problem, and the Hubble tension. In this paper, we propose a novel effective field theory model that resolves these paradoxes not as isolated anomalies, but as a single thermodynamic consequence of "scale maintenance" of local matter systems in an expanding spacetime. We formulate the "Conformal Maintenance Power" (Pconf ∝ H²)—the continuous energy dissipation required for quantum bound systems to maintain their intrinsic scales against the geometric deformation of the Hubble flow—as an interaction Lagrangian between matter and the vacuum field. In this framework, dark energy is not an a priori cosmological constant, but a dynamically emergent field accumulated from the dissipation heat of matter via geometric friction. Applying this framework to the cosmic history, we show that the explosive energy dissipation in the early universe (reheating phase) followed by a rapid freeze-out mechanism naturally cancels the 120-order-of-magnitude discrepancy from the Planck scale without artificial fine-tuning. Furthermore, through phase-space analysis of the dynamical system, we mathematically prove that the system possesses a stable scaling attractor trajectory that tracks the matter density, explaining the present-day energy "coincidence" as an inevitability. Finally, we demonstrate that the late-time decoupling of the interaction induces an observationally "apparent phantom dark energy" (weff < -1), which seamlessly relieves the Hubble tension between high-redshift (CMB) and local (SNIa) measurements. This theory introduces a new paradigm where microscopic quantum geometric limits drive macroscopic cosmic expansion, offering clear, testable signatures for next-generation cosmological observations.
