Cadmium-Amplified Torsion Phase Shift in Neutron Interferometry: A Direct Test of G-MaTT

Abstract We present a first-principles derivation of the cadmium-amplified torsion phase shift in neutron interferometry within the Generalized Mass as Twisted Time (G-MaTT) framework. In G-MaTT, the neutron accumulates a tiny intrinsic phase due to the background primordial mass-time torsional potential \(\mathcal{M}_\mu\). This phase is undetectably small (\(\sim 10^{-14}\) rad) under normal conditions. However, when a cadmium absorber is placed in one path, it triggers the Twist–UnTwist (TUT) desynchronization mechanism, which amplifies the phase shift by a factor of \(\mathcal{A} \approx 3.2 \times 10^{10}\), yielding a measurable signal of \((3.2 \pm 0.4) \times 10^{-3}\) rad—consistent with preliminary FRM-II data. This effect is unique to G-MaTT and provides a direct, tabletop probe of Planck-scale torsion geometry.
