CoreLumen Cosmology VI : Phase Attractor Dynamics

This work presents the late-time cosmological structure of the CoreLumen condensate framework. Within the CoreLumen program the physical vacuum is modeled as a phase condensateΨ = ρ e^{iθ}, whose phase dynamics governs the effective gravitational responseof the vacuum sector. In this paper we analyze the late-time attractor structure of the condensatecosmology and demonstrate how the phase-driven vacuum dynamics naturally producesa cosmic acceleration phase without introducing an explicit cosmological constant. The analysis focuses on the structural properties of the condensate attractor,its dynamical stability conditions, and its role within the broader architectureof the CoreLumen vacuum–gravity–cosmology program. This document is released in Zenodo archival mode. It serves as a theoreticalrecord of the structural formulation rather than a journal submission orprecision observational fit. The CoreLumen research program develops a condensate-based description ofvacuum structure, gravity, and cosmology organized across multiple series:Vacuum, Gravity, Cosmology, Observational Program (COS), and Fundamental Physics.
