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 interest is mathematical quantum 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 mathematical aspects of the BCS theory of superconductivity and the mathematics of dilute quantum gases. For more information see my CV.
