Figure 3
Schematic illustrations of the rotation of the Euler angle ϕ about the rotation axis of a particular symmetry element (C4). (a) In a single box, the amplitudes of the displacements oscillate as a function of ϕ. (b) For random displacements across multiple subcells or boxes, the amplitude averages to a constant value as a function of ϕ with a high and constant variance (denoted by error bars). (c) For displacements towards the four corners, the amplitude averages to a constant value as a function of ϕ, but the variance oscillates as a function of ϕ angle.
