People do the analog with BECs. Look up BECs and, perhaps, Gauss-Laguerre beams, though there are other ways to rotate them. Like superfluids, BECs don't rotate in the usual way. Instead, vortices are quantized and the vortices pack. http://en.wikipedia.org/wiki/Bose%E2%80%93Einstein_condensate#Vortices http://en.wikipedia.org/wiki/Bose%E2%80%93Einstein_condensat...
