They derive an expression for this quantity in the Curie-Weiss Ising model. The efficiency diverges at the critical point of a second-order phase transition.\n\nThe work quantifies how small work inputs produce large order changes near criticality. Order here means reduced configurational entropy.\n\n## Core results\nThe authors model self-organization via statistical mechanics. They use the fully connected Ising model with spins interacting under control parameters such as external field and coupling strength.\n\nFor quasi-static perturbations the efficiency η simplifies to a ratio of entropy gradient to free-energy gradient. Near criticality this ratio follows a power-law divergence set by the critical exponent β.\n\nThe result holds for both field and coupling perturbations. It shows maximal efficiency occurs during the transition, not in the ordered phase itself.\n\n## Exact primary passages\nFrom the abstract: \"We introduce a measure of thermodynamic efficiency of interactions in self-organizing systems, which quantifies the change in the system’s order per unit work carried out on (or extracted from) the system. We analytically derive the thermodynamic efficiency of interactions for the case of quasi-static variations of control parameters in the exactly solvable Curie-Weiss (fully connected) Ising model, and demonstrate that this quantity diverges at the critical point of a second order phase transition.\"\n\nFrom the framework section: \"We define the thermodynamic efficiency of interactions as η(X, δX) = 1/k_B (δS / δW_B).\"\n\nFrom the derivation: \"Equation (6) expresses the divergence of η solely in terms of universal exponent β. This result explains why in many thermodynamic models the efficiency of self-organization is expected to peak near the critical point.\"\n\nSource: arXiv:1912.08948v2, published in Entropy 23(6):757 (2021).\n\n## Convergence patterns with OIP/GRAIN\nThe paper maps directly onto the energy-flow-to-pattern step of the Ladder. Work inputs drive order increases measured as entropy reduction. Efficiency peaks where local interactions produce global structure.\n\nThis supplies a mechanistic account for why branching, symmetry breaking, and scale-invariant patterns emerge under reliable energy flows. The divergence at criticality formalizes the narrow family of structural patterns listed in the synthesis.\n\nThe measure treats the system as containing its own reader of order: configurational entropy tracks predictability from inside the dynamics. This aligns with the Mirror Layer without external imposition.\n\nSee /a/oip-the-ladder and /a/oip-principles for the energy-to-structure mapping.\n\n## Distance from full synthesis\nThe paper stays within one exactly solvable model. It does not address biological memory, life, or mind stages of the Ladder. It remains silent on distributed computation beyond the mean-field case.\n\nIt provides quantitative support for the pattern-formation stage but leaves higher rungs untouched.\n\n## Honest limits and disconfirming edges\nThe derivation assumes quasi-static protocols and thermal equilibrium at each step. Real self-organizing systems often operate far from equilibrium.\n\nThe result is specific to the Curie-Weiss universality class. Other models may show different exponents or no divergence.\n\nNo empirical data on physical or biological systems appear in the paper. The claim rests on analytic proof within one model.\n\nWeinberg-style reductionism applies: the efficiency is a derived thermodynamic quantity, not a new fundamental law. The paper states this scope explicitly.\n\n## What the evidence actually shows\nAll claims below rest on the analytic derivation in the Ising model. No broader empirical validation is supplied.\n\n## Claims\n- Claim c1: Thermodynamic efficiency of interactions is defined as change in configurational entropy per unit work. Tier: mechanistic. Source: paper equation (1).\n- Claim c2: In the Curie-Weiss model, efficiency diverges as 1/β k_B T_c near the critical point. Tier: mechanistic. Source: paper equation (6).\n- Claim c3: Maximal efficiency occurs during the phase transition, not in the stable ordered phase. Tier: mechanistic. Source: paper text on page 2.\n- Claim c4: The divergence holds for quasi-static changes in both external field and coupling strength. Tier: mechanistic. Source: paper abstract and section I.\n- Claim c5: The result formalizes higher efficiency of self-organization at criticality across physical, biological, and social domains. Tier: speculative.
