2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/125736We will describe a new superconductivity mechanism, proposed by the authors in [1], which is based on a topologically ordered ground state rather than on the usual Landau mechanism of spontaneous symmetry breaking. Contrary to anyon superconductivity it works in any dimension and it preserves P-and T-invariance. In particular we will discuss the low-energy effective field theory, what would be the Landau-Ginzburg formulation for conventional superconductors.invited review, to appear in "Superconductivity Research Advances", Nova Publishers, 32 pagesHigh Energy Physics - Theorytext
