Fig. 4
Elastic multipoles induced by a pair of dissimilar particles. a–d Textures of a sample with particles in a nematic cell obtained by optical polarizing, (b) with and (a) without a retardation plate, and (c, d) bright field microscopy. Top particle has planar and bottom particle has homeotropic anchoring. e–g Schematic diagram (blue lines) of n(r) (g) also calculated in (f) and (e) corresponding color-coded diagram of the nx directly at the surface of the particle shown in (a–c) and at the surface of the interpolation sphere. Inset shows a corresponding atomic orbital. h Schematic diagram of n(r) around a pair of particles shown in (d). Scale bar: 5 μm
