Stupid question: could one recursively stack and twist these layers and ultimately join the head with the tail while keeping the property of "each layer is twisted in relation to the previous"?
I mean twisting each layer with the magic angle, and adding on top of the previous, and so on, until the very first layer is a suitable successor of the topmost layer.
This kind of stack could be made into a magically twisted graphene donut.
Maybe the construction would be completely useless, but a research paper with a title containing "magically twisted graphene donut" is a win nevertheless.
- AaronFriel 7y agoIf you imagine this torus with flat sheets projected out from the innermost annulus, then the distance between the sheets would increase as you get further out. I wonder how far apart the sheets can be before the effect breaks down.
- jnurmine 7y agoI see what you mean. To avoid the sheets being too far apart, the torus would have to have a big radius. And then the non-torus stack of sheets would have to repeat many times i.e. it would have to be very long. Maybe there's a better topology to make some kind of a loop of the twisted stacks...
