Solitons: From charge density waves to FFLO in superconductors

This short review aims to summarize on “what the charge density waves can tell to other inhomogeneous states in strongly correlated systems, particularly to spin-polarized superconductors”. We shall update on expanding observations of solitons in quasi 1D CDW conductors and link them to the growing information and demands related to inhomogeneous spin-polarized states in superconductors. The related theory, existent or awaited for, stretches from solitons in 1D models to vortex-like elementary excitations in 2D, 3D ordered incommensurate CDWs and superconductors.
