Figure 2.

Schematic diagram of a tilted and left-handed cholesteric domain a) before deformation, b) after a unidirectional compression along $\widehat{\mathbf{z}}$ scaling with a factor $\alpha$, c) after redefining the helical axis as ${\widehat{\mathbf{m}}}^{\prime }$. The directors $\widehat{\mathbf{n}}$ and ${\widehat{\mathbf{n}}}^{\prime }$ are depicted by double-headed arrows (in blue) to account for their symmetry by inversion.
