Janus nematic colloids

Abstract:

We study the behavior of Janus colloidal particles in the nematic liquid crystal 5CB using polarizing optical microscopy and Landau-de Gennes (LdG) modeling. Different equilibrium orientations of Janus particles and different director field configurations around them are observed, depending on the preparation technique of homeotropic (DMOAP) and planar (Au) hemispheres. Using laser tweezers we measure the interactions between different orientations of Janus nematic colloids, showing a boojum ...
