In this talk I will give a pedagogical overview of the theory of 1D topological superconductivity induced by ferromagnetic metal chains. After a brief introduction of the Kitaev model, which is the cornerstone of this topic, I will explain the basic physics of Shiba states, namely subgap states induced by local magnetic moment in a superconductor, and their relevance in the context of Kitaev model. The focus then will be shifted to experimental realizations based on ferromagnetic adatoms and conventional superconductor, where specific, yet important, physical issues beyond the generic (Kitaev) model will be discussed.
