The proposed school aims at providing the scientific community (PhD students, postdocs, young researchers, experimentalists, researchers wishing to change field,...) with a comprehensive description of He-Density Functional Theory (He-DFT), a bosonic counterpart to electronic DFT, as applied to liquid He-4 and droplets, as well as a basic tutorial of the accurate and user-friendly computing suite for the static and dynamic description of doped helium droplets. The ultimate goal is to bring the attendants to master the He-DFT method and computing tools required to interpret front-edge experiments and design new ones in this field.
