Description
In recent years, an alternative to the standard ΛCDM model has emerged known as Fuzzy Dark Matter (FDM). We discuss how FDM, characterized by ultra-light bosonic particles with masses on the order of 10^{-22}eV, arises within String Theory constructions, particularly those involving axion-like fields. We study how FDM influences structure formation on astrophysical scales, leading to a suppression of structure formation below a certain threshold, which could resolve several small-scale discrepancies inherent in the ΛCDM model. In this study, we explain how it can be effectively modeled as a non-relativistic quantum system.
