Theory of Complex Fluids

Complex fluids (or soft matter), is a general term referring to a broad class of materials, which are neither molecular liquids nor atomic or molecular crystals. Examples include surfactant solutions, polymer solutions, interfacial monolayers, membranes, suspensions, and liquid crystals. The rich phase behavior and dynamic response of such materials stem from the existence of inner structures on an intermediate, nanometer-to-micron scale, between the molecular and the macroscopic scales (e.g., micelles, colloid particles, polymeric structures). The theoretical challenge is to account for the emergence of these structures, their effect on material properties, and their various instabilities.
In the past several years we have been focusing on the dynamics and flow properties of complex fluids, and on various effects caused by micro- and nano-scale confinement. Recently studied systems have included: (a) colloid suspensions in narrow channels; (b) heterogeneous fluid membranes; (c) particle-encapsulating vesicles; (d) curved liquid domains; (e) compressed surfactant monolayers; (f) surfactant aggregates (micelles); (g) liquid quasi-crystals.
