Derivation of Ginzburg-Landau theory for a one-dimensional system with contact interaction Frank, Rupert L Hainzl, Christian Robert Seiringer ; https://orcid.org/0000-0002-6781-0521 Solovej, Jan P In a recent paper [7] we give the first rigorous derivation of the celebrated Ginzburg-Landau (GL)theory, starting from the microscopic Bardeen- Cooper-Schrieffer (BCS)model. Here we present our results in the simplified case of a one-dimensional system of particles interacting via a δ-potential.
