The role of self-consistency in Bogoliubov-de Gennes equations is frequently underestimated in the investigation of in-gap states created by magnetic impurities in s-wave superconductors. Our research focuses on the impact of self-consistency on the in-gap states produced by magnetic stuctures on superconductors, specifically evaluating the density of states, the in-gap bands, and their topological attributes. Here, we show results ranging from single impurity to finite chains, and infinite ferromagnetic spin chains in wide-band s-wave superconductors. These results show that the order parameter contains important information regarding quantum phase transitions and their topological nature, underscoring the importance of self-consistency in such studies.
