Independent research program in scalar-refractive gravity and precision metrology; open to experimental collaboration on cavity–atom LPI and ion–neutral tests.

Overview

Density Field Dynamics (DFD) is a scalar-tensor framework in which a refractive field ψ governs both photon propagation (n = eψ) and test-mass acceleration (a = c²/2 ∇ψ). The theory reproduces standard post-Newtonian predictions in the weak-field limit while making distinct predictions for cross-sector gravitational coupling tests, including a predicted Local Position Invariance slope of ξ = 1 for cavity–atom frequency ratios.

This site archives preprints, data packages, and experimental proposals associated with this research program. All documents are preprints unless otherwise noted.
