Complex (dusty) plasmas are composed of a weakly ionized gas and charged microparticles
and represent the plasma state of soft matter. Complex plasmas have several remarkable …

Liquid foams can behave like solids or liquids, depending on the applied stress and on the
experimental timescale. Understanding the origin of this complex rheology which gives rise …

We present results on a series of two-dimensional atomistic computer simulations of
amorphous systems subjected to simple shear in the athermal, quasistatic limit. The …

Many fundamental issues in classical condensed matter physics can be addressed
experimentally using systems of individually visible mesoscopic particles playing the role of …

We present results on numerical simulations of an atomistic system undergoing plastic shear
flow in the athermal, quasistatic limit. The system is shown to undergo cascades of local …

We report on experimental measurements of the flow behavior of a wet, two-dimensional
foam under conditions of slow, steady shear. The initial response of the foam is elastic …

Experimental results on the dislocation dynamics in a two-dimensional plasma crystal are
presented. Edge dislocations were created in pairs in lattice locations where the internal …

Liquid foams are classified into a dry foam and a wet foam, empirically judging from the
liquid fraction or the shape of the gas bubbles. It is known that physical properties such as …

For crystalline materials, the microscopic origin of plasticity is well understood in terms of the
dynamics of topological defects. For amorphous materials, the underlying structural disorder …

Many physical systems exhibit plastic flow when subjected to slow steady shear. A unified
picture of plastic flow is still lacking; however, there is an emerging theoretical …
