Spin spiral models
Upon reading a research paper about spin spirals being generated by dipole-dipole interactions within a spinor Bose-Einstein condensate I thought it would be cool to design a physical object to represent the resulting spin spiral.
These objects represent the transverse spin rotation angle with distance along the quantisation axis of a 1D spinor Bose-Einstein condensate with dipole-dipole interactions, as shown in figure 1 of the paper linked above. There is a separate spin spiral for different evolution times where the spiral gets more twisty for longer evolution times.
The included models are 10cm tall, but there is also a customisable version where the height, width and thickness of the spiral can be varied.
