|Parallel Transport along Closed Loop Doesn't Meet!|
Blue Phase Parallel Transport has
Negative Curvature in Flat Space
Rijij = -6 q^2
On sphere of radius 1/q in four dimensions, the curvature vanishes!
There is an ideal template for double-twist there:
|The Blue Phase is like a carpet made of orange peel (figure copyright Pamela Davis Kivelson): the edges of the cuts are the defect lines.|
