Q Field Cosmology Simulation Code

This repository contains Python scripts and data supporting the companion paper submitted to Entropy, titled “A Quantum-Coherence Field for Cosmic Structure, Expansion, and Gravity” The scripts demonstrate how a scalar coherence field Q(x,t), motivated by entanglement dynamics and decoherence theory, can reproduce core features of ΛCDM cosmology without invoking dark matter or a cosmological constant. Each script corresponds to one figure from the manuscript and illustrates specific aspects of the Q field dynamics: Figure 1: Local coherence loss in a quantum spin chain (entanglement gap). Figure 2: Early universe expansion from probabilistic coherence spreading. Figure 3: Emergent structure from nonlinear coherence generation. Figure 4: Void-driven particle repulsion due to Q field decay. Figure 5: Comparison of Q field expansion history to ΛCDM. The code is written in Python 3.10+ and uses NumPy, SciPy, Matplotlib, and QuTiP (for Figure 1). It is intended for conceptual illustration and research reproducibility. Scripts are self-contained and numerically validated but not cosmologically calibrated. Intended Use:This dataset is suitable for researchers working on quantum gravity phenomenology, emergent gravity models, analogue gravity, scalar field cosmology, and information-based approaches to spacetime.
