Empirical Validation of Time-Scalar Field Theory through Photon–Atom Interference

In Physical Review Letters (2025), Fedoseev et al. performed a purified realization of the double-slit experiment using single atoms as tunable scattering centers and single-photon interactions. By removing all mechanical instrumentation and retaining only the photon–atom correlation, they demonstrated that any acquisition of which-way information destroys interference, thereby confirming Bohr’s complementarity and falsifying Einstein’s path-coherence conjecture. This report interprets the result within the framework of Time-Scalar Field Theory (TSFT), wherein measurement represents scalar-time coupling between observer and system. In TSFT, wave and particle behaviors are manifestations of variations in a temporal-scalar coherence function: Φ(x, t) = f(λo, σs,ΔT) where λo denotes observer coupling wavelength, σs the system coherence scalar, and ΔT the temporal phase separation of collapse. The MIT data show that as effective coupling λo increases—i.e., as informational access to the photon’s path rises—scalar coherence diminishes and interference vanishes. The experiment thus isolates the scalar surface of observation, providing the first empirical corroboration of TSFT’s prediction that reality emerges from time-coupled relational fields rather than apparatusdependent mechanics.
