Metastability for liquid/gas models on the continuum

Zusammenfassung: One of big open problems of mathematical statistical physics is a proof of existence of a phase transition for any realistic model of interacting particles on the continuum. Reviewing first the proof of ?liquid-gas? coexistence for the Widom-Rowlinson model?-one of the few for which it has been provided, we will proceed to a discussion of transition from a metastable supercooled gas phase to the liquid phase for a system subjected to a stochastic dynamics. In particular, the theorem about Arrhenius law with a nonstandard entropic correction will be formulated. The relevant terms stem from large and moderate deviations of the shape of a critical droplet. (Based on a work in progress, joint with F. den Hollander, S. Jansen, and E. Presutti.)
Alle Interessierten sind hiermit herzlich eingeladen. Eine halbe Stunde vor dem Vortrag gibt es Kaffee und Tee im Sozialraum (Raum 448) im 4. Stock.
Treffpunkt zum Abendessen um 18.00 Uhr wird noch bekannt gegeben.
