Relaxation-Driven Cyclic Cosmology v1.14: A Minimal Eternal Model with Emergent Tilt and CPT-Conjugate Mirror Sector

Title:Relaxation-Driven Cyclic Cosmology v1.14: A Minimal Eternal Model with Emergent Tilt and CPT-Conjugate Mirror Sector Description/Abstract: Relaxation-Driven Cyclic Cosmology (RDCC) is a nonsingular, eternally cyclic cosmological model based on a single effective complex scalar order-parameter field evolving in a tilted double-well potential. The tilt arises emergently and technically naturally from radiative Coleman-Weinberg corrections, requiring no ad-hoc parameters or fine-tuning. Field relaxation within the asymmetric potential generates a time-varying vacuum energy, driving alternating phases of accelerated expansion and contraction in an eternal "breathing" cycle. A gravitationally coupled CPT-conjugate mirror sector with reversed thermodynamic arrow provides an effective cold dark matter contribution and resolves the baryon asymmetry through phase-induced mechanisms (matter excess in our vacuum, antimatter excess in the mirror). Global CPT symmetry is exactly preserved, realized through locally asymmetric conjugate vacua—a natural dual structure that suppresses cycle-to-cycle memory via dynamical attractor behavior. The framework operates as an effective field theory on cosmological scales, avoiding singularities, entropy divergence, flatness issues, and the need for inflation or modified gravity. Primary observational predictions include an enhanced late-time Integrated Sachs-Wolfe effect ($\sim$12% excess in low-$\ell$ CMB power), primordial perturbations generated by the bounce, and a stochastic gravitational wave background detectable by future instruments such as LISA. Additional signatures include mild suppression of small-scale power, characteristic modulations in the 21-cm signal, and a stochastic gravitational wave background from the bounce. Version 1.14 notes:Added explicit resolution of the Hubble tension, solution to the core-cusp problem via mirror perturbations, and dualism as a unifying principle for apparent opposites.
