Structures of passive and active nematic defects

Povzetek / Abstract:

Complex –passive or active- nematic fluids are characterised by internal orientational order, which upon tuning or frustration, can exhibit topological defects. Here, we present structures of topological defects in passive and active nematic complex fluids.
Specifically, we show in passive nematics how confinement in the form of complex geometry and fractal surfaces can lead to formation of various defect-based nematic profiles, including exhibiting high-elastic multipoles. In active nematics, we show defect profiles in three-dimensional active nematic droplet, also highlighting the role of different surface coupling regimes.
