Ginzburg and Landau: on the theory of superconductivity

What changed

Developed a phenomenological order-parameter theory of superconductivity with coupled equations for spatial variation and electromagnetic response near the transition.

Scientific scope

The record is the exact 1950 Zhurnal Eksperimentalnoi i Teoreticheskoi Fiziki paper. Landau phase-transition theory, the later microscopic derivation, Abrikosov vortices, BCS theory and modern Ginzburg–Landau applications remain separate.
