A branched transport limit of the Ginzburg-Landau functional
A branched transport limit of the Ginzburg-Landau functional
We study the Ginzburg-Landau model of type-I superconductors in the regime of small external magnetic fields. We show that, in an appropriate asymptotic regime, flux patterns are described by a simplified branched transportation functional. We derive the simplified functional from the full Ginzburg-Landau model rigorously via Γ-convergence. The detailed analysis …
