Structural Differentiation Quantum Theory (SDQ): A Minimal and Falsifiable Framework for Decoherence, Measurement, and Structural Dynamics

Structural Differentiation Quantum Theory (SDQ) presents a minimal and falsifiable reformulation of quantum decoherence and measurement. In SDQ, decoherence is not interpreted as environmental noise, but as the irreversible loss of structural connectivity within a closed relational system. A unified structural correlation function, S(L_s, t) = S_0 exp(-βL_s) exp(-γt), describes how both structural distance and structural time govern the decay of quantum correlations. This framework reinterprets key quantum concepts:- Decoherence as structural dilution- Measurement as irreversible structural path selection- Time as the record of structural evolution A central prediction of SDQ is that decoherence is not universal, but depends explicitly on structural connectivity: γ_eff = γ_0 + κL_s This leads to a single decisive, directly testable, and experimentally falsifiable criterion distinguishing SDQ from standard quantum mechanics. By connecting structural dynamics to observable quantities, SDQ establishes a direct bridge between theoretical formulation and experimental verification.
