Physical Processes Underlying Ginzburg-Landau Theory: Energy Competition, Condensation Saturation, and Cooper Pair Inertial Mass Scaling Laws

Abstract

The Ginzburg-Landau (GL) theory provides a successful phenomenological description of superconductivity near T_c through parameters α, β, and m^*. However, a unified physical interpretation of these parameters, transcending specific microscopic mechanisms, is needed to understand commonalities across diverse superconducting families.

This work develops a conceptual framework by bridging GL phenomenology with microscopic theory through scaling analysis and coherence length correspondence. The approach involves deriving the complete set of scaling laws from the GL free energy functional and establishing self-consistency constraints among the fundamental parameters.

The analysis establishes T_c ∝√(-α/m^*) as an efficiency metric for superconducting ordering. Theoretical self-consistency requires the parameter constraints -α∝ m^* and β∝ m^*, revealing that material-dependent variations in these interconnected parameters, rather than their absolute scales, govern superconducting diversity.

The tripartite framework—encompassing energy competition (α), condensation saturation (β), and collective inertial response (m^*)—provides a unified physical picture that maintains mathematical consistency with GL theory. This picture can be substantiated by deeper physical mechanisms: energy competition may originate from matter-wave interference leading to energy redistribution, condensation saturation admits a geometrodynamic interpretation as an effective centrifugal confinement, and inertial mass enhancement can arise from orbital angular momentum coupling to local electric fields. Together, they offer qualitative design principles for optimizing superconducting materials across different families.
