Abstract

Granular systems, such as a bucket of sand, are composed of millions to billions of individual particles. Given the success of statistical physics, it seems to suggest itself to try to expand it in order to include granular matter.  In this process we have to account for the finite size of granular particles which gives rise to a number of properties, such as energy dissipation or friction, that do not play a role in the statistical mechanics of atoms or molecules.  While this idea of a granular statistical mechanics has been rather successful for granular gases, we seem to have hit a roadblock for granular solids. This talk will look into some of the theoretical, psychological, and experimental issues that need to be resolved (at least if we assume the whole endeavor isn’t doomed anyway).

BIO 

Dr. Matthias Schröter obtained his PhD in 2003 from the University of Magdeburg for his studies on electrochemical pattern formation. During his postdoctoral stay with Harry Swinney at the Center for Nonlinear Dynamics at the University of Austin his research focused on the statics and dynamics of granular media. In 2008 he joined the MPI for Dynamics and Self-Organization as a group leader, since 2015 he is an associated researcher. Main research topics are the statistical mechanics of granular media, X-ray tomography of complex materials and applications of machine learning in physics.
