First Universal Dissipation Bound in Superconductor Electrodynamics: Quantitative Diagnostic Framework and Cross-Material Validation of the Maxwell-Scretching Electromagnetic Closure

Description This dataset accompanies the research paper reporting the discovery of the first universal dissipation bound in superconductor electrodynamics through systematic analysis of the Maxwell-Scretching (MS) electromagnetic closure framework. Key Findings The dataset supports four principal discoveries: Universal Compensation Invariant: A novel dissipation bound σ̂₁,SC < ω with 100% compliance across all tested materials (compliance ratios 10⁻⁷ to 10⁻⁶) Reactive Channel Identity-Level Closure: Surface reactance scales linearly with London penetration depth (R² = 0.999991) with 0.13% theory-experiment agreement Quantitative Dissipation Diagnostic Map: Surface resistance correlation (R² = 0.78) isolating gap symmetry and multiband effects Frequency-Domain Validation: Sub-linear power-law scaling in niobium impedance measurements Materials Covered Type-I Superconductors: Nb, Pb, Al Type-II Cuprate: YBCO Multiband Superconductor: MgB₂ Dataset Contents Tabulated microwave frequency measurements for five superconducting materials Multi-frequency impedance data for niobium (1 kHz–1 MHz, 2.0–12.0 K) Regression analysis results and statistical validation metrics Maxwell-Scretching closure calculations and diagnostics Model-free observable extraction protocols (η = 2Rs/Xs) Technical Specifications Temperature ranges: 2.0–12.0 K (Nb impedance); material-specific Tc ranges Frequency ranges: 1 kHz–1 MHz (impedance); microwave (tabulated data) Permittivity spans: |ε'r| ~ 10⁸ to 10¹³ Validation includes Monte Carlo uncertainty analysis Applications This dataset enables: Quantitative diagnostics separating Maxwell-London deterministic channels from microphysical effects Systematic materials characterization without empirical BCS fitting Validation of electromagnetic closure theories across superconductor classes Development of R² thresholds for closure-grade versus microphysics-dependent response Methodology Analysis employs systematic regression against Maxwell-Scretching predictions, establishing quantitative thresholds (R² > 0.9999 for closure-grade; R² < 0.8 for microphysics-dependent channels) through cross-material validation spanning Type-I, Type-II, cuprate, and multiband superconductors.
