PhD thesis: “Van der Waals dispersion interaction between atoms and small molecules in ultracold environments”
Supervisor: Prof. A. Buchachenko
Giorgio Visentin graduated in Photochemistry and Molecular Materials in October, 20th,2017 from “Alma Mater Studiorum” University of Bologna and was admitted to Skoltech PhD in Physical Chemistry (track: Material Science and Engineering) on November, 1st, 2017. His PhD thesis regards devising accurate ab initio approaches to describe atom-atom and ion-atom Van der Waals interaction. Up to date, he published the following articles:

Giorgio is now working on devising a new state-of-the-art potential for the Van der Waals Yb2 dimer, for applications to ultracold physics (e.g. Photoassociation Spectroscopy, Ultracold Scattering experiments).
