Claims

C1strongest claim

The resonant fraction is suppressed linearly with the Ising broadening Γ_Ising -- in contrast to the quadratic suppression of conventional relaxation-time approximations. This single emergent scale yields a fit-free renormalization, T_r^{corr} ≃ T_r^{orig} Γ_Ising / σ_exp, which quantitatively accounts for the anomalous scaling T_r ∝ r^{4.5} in three-dimensional superradiant masers.

C2weakest assumption

That configuration-dependent diagonal Ising interactions dominate the pair detuning ε_ij and set the transport bottleneck, with no significant contributions from other sources of decoherence, higher-order interactions, or non-dipolar effects in the disordered ensemble.

C3one line summary

Ising blockade detunes spin pairs via correlated diagonal interactions, suppressing resonant fraction linearly with broadening and yielding a fit-free renormalization that accounts for T_r ∝ r^{4.5} in 3D masers and T_r ∝ r^3 in 2D.
