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

This work investigates whether a Symmetron-like implementation of the Local Relative Acceleration Expansion (LRAE) is consistent with current experimental constraints from atomic clocks and Solar System tests. A Symmetron-type effective potential is used, and a numerical parameter space scan is performed. The results show that short interaction ranges and small self-couplings are excluded, while moderate to large ranges remain viable. Atomic clocks consistently provide stricter bounds than Cassini data. Hence, the LRAE can be reconciled with precision experiments through a density-dependent screening mechanism.
