      abstract     = {There are several types of shear-induced instabilities in
                      soft-matter systems. The microscopic origin of some
                      well-known instabilities will be shortly addressed. A
                      shear-induced instability that is not yet understood is the
                      so-called “Shear-gradient Concentration Coupling
                      instability” (the SCC-instability). This instability
                      relies on the existence of a shear-gradient induced mass
                      flux together with a strong coupling of the stress to
                      concentration. The origin of the shear-induced mass flux
                      resulting from direct interactions is so far not understood,
                      and explicit expressions for the corresponding transport
                      coefficient have therefore not been derived. In this
                      presentation, the origin of this mass flux is discussed, an
                      explicit expression for the transport coefficient is
                      presented, and numerical results are discussed for the
                      stationary non-uniform flow profiles and concentration
                      profiles of an initially SCC-unstable system, which will be
                      compared to experiments on hard-sphere glasses.},
