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.
I took a screenshot of figure 1(g) from this research paper and ran it through a web app which allowed me to extract the data points. I then fed the data into MatLAB, smoothed it, interpolated uniformly spaced vectors of the angular change between each data point then output some code which could be compiled with OpenSCAD. The completed spin spiral is a series of twisted linear extrusions whose angles match those detailed in the initial figure.
