FIG. 3.29 The energy dispersion for a Chern insulator in a semi-infinite nanoribbon. The edge states are shown via the red lines that split from the bulk. In the yellow panel below, we show the chiral edge currents that flow in opposite directions along these edge modes.

Published: July 2022
FIG. 10.9 (a) Confocal microscopy image of a DPPC monolayer on a flat interface in a Langmuir trough. Contrast in the image is by the preferential segregation of Texas Red DHPE dye to the disordered liquid phase that appears red in the image. The dye is excluded from the semi-crystalline solid phase that appears black. The counterclockwise rotation of the domain arms is due to the chiral center in the native DPPC. The domain sizes are comparable to alveolar dimensions. (b) Compared to the DPPC morphology on a 70 μm diameter bubble. The domains shape changes dramatically to extended interconnected micrometer width stripes. The images were taken at the same surface tension and conditions, the only change is the curvature of the interface.
