The unity of physics: the beauty and power of spectroscopy — •Paul Julienne — Joint Quantum Institute, College Park, Maryland, USA

Physics exhibits a deep unity across all its disciplines. This is nowhere so evident as in the power of spectroscopy, the highly specific frequency dependent interaction of light with matter, to inform us about a wide range of phenomena. We rightly honor Professor Eberhard Tiemann today for his beautiful applications of spectroscopy to essential science needed for ultracold matter studies. His work on molecular potentials enables highly predictive models to be developed for the interactions of magnetically controllable ultracold atoms. I will illustrate this for the specific case of the unusual three-body physics of potassium atoms done in collaboration with theorist Jose D'Incao and experimental studies from the groups of Eric Cornell and Jun Ye at JILA. The precise molecular potentials of potassium dimer molecules that came from Professor Tiemann's group are essential to the theory. Ultracold matter studies across a wide range of phenomena would not be as successful as they have been without such detailed and accurate knowledge of atomic and molecular interactions that is only made possible through conventional and novel spectroscopic tools and analysis.
