Andreas Deuchert

Andreas Deuchert portrait I am currently a post-doc in the Seiringer group at the Institute of Science and Technology Austria (IST Austria) (since October 2016). My main research interests are mathematical quantum mechanics and quantum statistical mechanics. More specifically I am applying techniques from Analysis and Functional Analysis to problems coming from condensed matter and cold atom physics. Two important themes in my work are the mathematics of dilute Bose gases and mathematical aspects of the BCS theory of superconductivity. For more information see my CV.
