This repository contains the full manuscript, figures, and numerical scripts supporting the paper:
“Beyond ΛCDM: The CPT-Siamese Phase Mechanism as a Unified Solution to the Dark Energy, H₀ and σ₈ Tensions.”
This work introduces a CPT-symmetric Siamese cosmology in which dark energy emerges dynamically from vacuum phase desynchronization, rather than from a fundamental cosmological constant. A single phase-interference mechanism simultaneously addresses:
- The H₀ tension
- The σ₈ structure growth tension
- Late-time cosmic acceleration anomalies
- The apparent breakdown of ΛCDM at low redshift
The model predicts a transient acceleration phase followed by asymptotic deceleration, in qualitative agreement with recent observational trends.
This repository explicitly includes:
- ✅ The full paper (PDF)
- ✅ The Python script used to generate Figure 1
- ✅ The comparative H(z) vs. z plot between ΛCDM and Siamese cosmology
- ✅ All material required to numerically reproduce the central observational result
Figure 1 corresponds to the Hubble expansion comparison H(z) between ΛCDM and CPT-Siamese cosmology.
The two additional diagnostic figures used in the paper:
- Expansion Turnover: H(z)/(1+z)
- Deceleration Parameter: q(z) vs Son & Lee (2025)
are fully reproduced in the companion reproducibility dataset hosted at:

“siamese-cosmic-deceleration: Replication Data & Code for
‘Transient Cosmic Acceleration from Phase Interference: A Siamese Cosmology Confronted with Son & Lee (2025)’”
That companion repository contains the complete numerical pipeline required to reproduce Figures 2 and 3 of the present paper.
All scripts are provided to ensure:
- Full numerical transparency
- Independent verification
- Open, reproducible scientific workflows
