Beyond ΛCDM: Power Spectrum Deviations from General Coherence Field Theory

This record presents the results of cosmological simulations performed with a modified version of the CLASS Boltzmann solver, implementing the General Coherence Field Theory (GCFT). The accompanying manuscript describes theoretical motivations, numerical methods, and direct comparisons between GCFT and ΛCDM matter power spectra. Our results show that GCFT reproduces standard cosmological predictions at large scales but predicts a suppression of small-scale power due to coherence-induced modifications to gravity. Figures and data files are provided for full reproducibility.

Included files:

• main.tex: Full LaTeX source of the manuscript.

• main.pdf: Precompiled manuscript PDF.

• fig1_gcft_vs_lcdm.png, fig2_relative_diff.png: Figures for power spectrum comparison and relative deviation.

• GCFT00_pk.dat: Raw simulation output for GCFT matter power spectrum.

• README.txt: Brief guide to files and reproduction instructions.

This work is intended as a standalone technical note and as a supplement to the main GCFT theoretical framework (see https://zenodo.org/records/16044348).
All files are released for open research and community validation. Please cite this record if using these results or data in your work.
