Out-of-equilibrium response of soft and biological matter to forces and deformation — •Claus Heussinger — Institut für theoretische Physik, Universität Göttingen

In the talk I will give a few examples from our research concerning the complex dynamical response of soft and biological materials to perturbations via forces or deformation. The systems we study are, in general, far from thermal equilibrium. Phenomena will range from the emergence of flow instabilities (shear-banding, rheo-chaos) in complex fluids, over the visco-elasto-plastic behavior of biological cells and their sub-cellular components, to the fluid-to-solid jamming transition in a-thermal granular particles. The goal is to define suitable model systems where the relevant physical mechanisms can be identified and understood. To this end we use different simulation tools going hand in hand with analytical modeling and, whenever possible, experimental verification.
