| contents | <p><span>This preprint presents the Coherent Quantum Geometry Emergence (CQGE) model, a single scalar field derived from twisted geometry coherent states in Loop Quantum Gravity (LQG). Starting from the expectation value of the holonomy angle, we obtain a macroscopic coherence field C whose effective action is derived via coarse-graining of spin networks, without ad-hoc dissipation. The model modifies the Loop Quantum Cosmology (LQC) Friedmann equation and predicts a softened quantum bounce (rho_bounce = 0.82 rho_c), a superinflationary phase with about 70 e-folds, and late-time acceleration (w_eff ≈ -0.15). A rigorous stability analysis shows no ghosts, tachyons, or superluminal modes. Using a modified CLASS Boltzmann code and Planck 2018 likelihood, we perform a full MCMC analysis, obtaining a reduced chi-square of 1.02 and a Hubble constant H0 = 73.2 ± 1.1 km/s/Mpc, thereby resolving the Hubble tension. The model also predicts log-periodic oscillations in the primordial gravitational wave spectrum. This work provides a complete, derivable, and testable bridge between LQG and cosmology.</span></p> |
