I am interested in the conceptual and mathematical foundations of quantum theory. Anything, in which the structure of quantum mechanics plays a non-trivial role, really. In recent years this has mostly been quantum information theory, but also quantum statistical mechanics and the theory of time in quantum mechanics. I like problems which are conceptually interesting and allow an answer in the form of a non-trivial theorem. As a mathematical physicist I also try to answer questions at their appropriate level of generality. Generally observed features of the theory, like, e.g., the approach of equilibrium in macroscopic systems, deserve a general explanation don't they?

Die AG Werner befasst sich mit den Grundlagen der Quantentheorie, besonders der Quanteninformationstheorie.
In jüngster Vergangenheit wurden besonders Mess-Unschärferelationen analysiert, sowie die topologische Klassifikation von eindimensionalen Quanten-Walks  unter diversen Symmetrieforderungen.
Aktuell ist eine Studie verschiedener Limiten der Quantentheorie in Vorbereitung. Unter einheitlichen Gesichtspunkten und mit verallgemeinerbaren Methoden sollen hier der klassische Limes, der Mean-Field Limes, sowie diverse Kontinuumslimiten und Renormierungsverfahren erfasst werden.
