From soft matter to 2D electron gases: Anomalous transport phenomena in heterogeneous media

Juergen Horbach

The Lorentz gas model is a paradigm for the understanding of fluid (electron) transport through heterogeneous media. In its simplest two-dimensional (2D) version, a point tracer explores the space between randomly distributed hard-disk obstacles which may overlap and are uncorrelated. In my talk, molecular dynamics simulations of Lorentz-gas models are presented that elucidate anomalous transport phenomena, as observed for colloidal and active particles in heterogeneous media as well as 2D electron gases in disordered arrays of antidots
