TRR 142 - Polaron signatures in the optical response of lithium niobate (B07*)
This joint theory-experiment project will explore the rich physics of polarons and their optical signatures. In particular, we plan to resolve their influence on the linear and nonlinear optical properties of the material as well as their condensation, hopping and dissociation characteristics in interaction with intrinsic and extrinsic point ...

Du Ch?telet's Philosophie und ihre Beziehung zu Leibniz und Wolff: ?bereinstimmungen und Unterschiede – Mercator Fellowship
Das hier vorgeschlagene Projekt will die detaillierte Erforschung von Du Ch?telets Verh?ltnis zu Leibniz und Wolff voranzutreiben. Du Ch?telets eigene Referenzen auf Leibniz und Wolff beziehen sich haupts?chlich auf ihre metaphysischen Grundlagen und damit auf einen Kern ihres Werkes, vor allem wenn man dieses aus philosophiegeschichtlicher ...

DemoKult – Die unterrichtsbezogene F?rderung von Kompetenzen für eine demokratische Kultur
Nicht nur aufgrund des Angriffskriegs Russlands auf die Ukraine steht das demokratische Selbstverst?ndnis in Europa spürbar unter Druck. Auch nationale Ereignisse (z. B. das Erstarken verfassungsfeindlicher Positionen in Parteien des Bundestags und der Landtage; extremistisch motivierte Anschl?ge in den letzten Jahren) verdeutlichen, dass ein ...
