Derivation of Ginzburg-Landau Theory for a One-dimensional System with Contact Interaction
In a recent paper  we give the first rigorous derivation of the celebrated Ginzburg-Landau (GL)the ory, starting from the microscopic Bardeen- Cooper-Schrieffer (BCS)mo del. Here we present our results in the simplified case of a one-dimensional system of particles interacting via a \( \delta \)-potential.
