Numerical Examination of LRAE Symmetron Parameters Against Atomic Clock and Solar System Constraints

This work presents a numerical investigation of the Local Relative Acceleration Expansion (LRAE) with Symmetron-type density-dependent screening. Static boundary value problems and dynamic relaxation runs demonstrate that the model is consistent with current atomic clock and Solar-System constraints. In Version 1.3, we add systematic parameter scans across $(\mu,\lambda)$, yielding contour maps of relative clock drifts and maximum allowed coupling strengths. The results confirm that realistic couplings predict drifts far below present detection thresholds. Full scan data are provided as supplementary CSV files.
