Nonlinear response to probe vitrification

The research unit investigates the combined effects of strong external fields and slow cooperative dynamics in glass-forming systems in order to understand the complex structural, relaxational, and transport phenomena under conditions far from equilibrium.

The projects of the research unit use strong mechanical and electric fields to obtain insights into the particle motion at the glass transition. Investigated materials range from supercooled alloys, colloidal dispersions, molecular glass formers to ionic fluids, granular media, and disordered media. Experimental techniques include mechanical, dielectric, and conductivity spectroscopy, while theoretical methods include variants of nonequilibrium computer simulations, mode coupling and kinetic theory, potential energy landscape, as well as continuous time random walk analysis.
