Abstract
Emulsions of isotropic liquids have spherical phase boundaries. Liquid crystals have elastic forces associated with the director distortions and preferred boundary conditions that can also play a role in defining the phase boundary shape. Here we show a liquid crystal in liquid crystal emulsion where a chemically distinct guest phase resides in the topological disclinations of the host phase. These disclinations act as effective capillaries and various meniscus and droplet phenomena are observed. This “topological capillary emulsion” shows that additional forces associated with anisotropic molecules can play a critical role in determining the shape and properties of a phase boundary.
