While real granular particles like sand, gravel, pills, cereals or coffee beans come in all sorts of shapes and are usually quite irregular, as a theoretician I exclusively use spherical (or disk shaped) particles. I prefer to solve problems with pen and paper (and the occasional help of Gradshteyn and Maple) but I also burn a lot of CPU time running and analysing… text/html 2018-07-02T15:30:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://wtkranz.de/dokuwiki/doku.php?id=start&rev=1530538243&do=diff Welcome I am Till Kranz, a research associate in the Institute for Theoretical Physics at the University of Cologne working on the DFG project Granular Matter: How Structure Determines Response Far From Equilibrium. My research focus is the theoretical description of nonequilibrium fluids in terms of their rheological properties. These fluids are characterized by a mechanism to dissipate energy and an text/html 2025-03-23T09:13:47+00:00 Anonymous (anonymous@undisclosed.example.com) https://wtkranz.de/dokuwiki/doku.php?id=teaching&rev=1742717627&do=diff Lectures * Physics of Granular Matter (SoSe 2025) with Jan Gabriel, Peidog Yu & Matthias Sperl * Introduction to the Physics of Granular Matter (WS 20/21) with Philip Born & Matthias Sperl * Physics of Granular Matter (WS 18/19) with Philip Born & Matthias Sperl * Advanced Statistical Physics (WS 16/17) with Matthias Sperl Planning text/html 2013-04-16T10:37:40+00:00 Anonymous (anonymous@undisclosed.example.com) https://wtkranz.de/dokuwiki/doku.php?id=topbar&rev=1366101460&do=diff * Home * Research * Granular Glass Transition * Granular Mixtures * Rough Spheres * Publications * CV
