From: Uncovering different states of topological defects in schlieren textures of a nematic liquid crystal
3D distribution of n around the defects with integer m. Calculated structures of defects with (a) m = +1 and (b) m = −1. Here the director n is the unit eigenvector of the tensor order parameter Q ij with the largest eigenvalue. The profile of n at the midplane of the cell is shown by rods. The brightness of the rod on the left is proportional to sin(2φ), where φ is the in-plane angle between the x (horizontal)-axis and (n x ,n y ). Shown on the right is a magnified view of the profile of n around the defect, where rods with the same n z are depicted with the same colour. (a) corresponds to the state [D,R,CW] shown in Fig. 1e and (b) to [D,N,R] shown in Fig. 1d.
