3rd International Workshop on
This workshop features lectures dealing with the nonlinear response of complex systems upon application of external perturbations, with contributions from groups dealing with experiment, computer simulation and theory. Examples are the response in strong external fields, non-linear rheology of dense complex fluids, plastic events in amorphous solids, or granular materials.
It is part of a series of workshops with this title and is sponsored by the DFG-Research Unit FOR 1394 "Nonlinear response to probe vitrification". The last workshop took place in Erlangen in 2013. Complex systems are characterized by many degrees of freedom with competing interaction. For understanding the highly complex dynamics it is extremely helpful to go beyond the linear response. A detailed characterization of the spatio-temporal nonlinear response to homogeneous and inhomogeneous perturbations contains important additional pieces of information about the underlying structural and dynamical properties. In macro-rheological experiments this amounts, e.g., to the understanding of shear thinning, shear thickening or the occurrence of shear bands. However, the full scope of the nonlinear response and the corresponding non-equilibrium behavior has yet to be fully explored.
This workshop will be a platform for discussions on recent developments in this active and multi-disciplinary field. By bringing together workers from these different fields, a fruitful exchange about the similar behaviors but also the differences, ranging from microscopic to macroscopic length scales, is envisaged.
