Extended Data Fig. 8

a, Intermediate friction (\(\xi=0.009\)) still exhibits a subset of handed defects. b, Snapshot of an ordered defect lattice for high friction (\(\xi=0.015\)), solely exhibiting mirror symmetric state +1/2 defects. Dashed lines show director field, solid lines \({\mathcal{Q}}=0\) contours, with enclosed area coloured by circulation (red for clockwise and blue for anti-clockwise). Blue trefoil symbols mark -1/2 defects and green comet-shaped symbols represent +1/2 defects. Data from Ref. 35.
