Metals in one spatial dimension are described at the lowest energy scales by the Luttinger liquid theory. Invented in 1992 by Steve White, the method was very rapidly adapted by the numerical many body methods groups around the globe. Kevin S.C. Decker, Christoph Karrasch, Jens Eisert, Dante M. Kennes We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system.
