Numerical modelling of layered complex fluids

Layered complex fluids, such as smectic liquid crystals, possess remarkable properties because of the geometric and topological consequences of layering: external forces lead to deformations of the fluid that are incompatible with the layering, leading to geometric frustration and the spontaneous assembly of a wide variety of textures. There has been a recent explosion of interest in exploiting the ability of smectics, as a paradigmatic example of a layered fluid, to repeatedly self-assemble over device length-scales. As we advance our theoretical and experimental understanding of these fluids, we may be able to develop highly attractive metamaterials for use as lenses, lithographic templates, or in other devices. However, the very complicated structures that emerge in these systems have proven to be extremely challenging to model computationally. We will bring together experts in experimentation, theory, and simulation, to focus on understanding the structures of these materials.
