That being said, I got halfway through this article and I’m still scratching my head as to what is meant by “twisting” here.
From the discussion of sheets lining up with one another, I assume they mean rotating one sheet relative to the other along a shared normal axis. But when I hear “twisting,“ I think of twisting these sheets like you would do to make a Mobius strip.
Neither the article nor the nice-looking illustration make this clear, so I’m off instead on a Google hunt so that I can conceptualize what’s being worked on here.
Edit: OK, this is pretty cool.
It’s always exciting when new theories are required to explain experimental results— doubly so here since this could yield insight into the physics of superconductivity, which we don’t understand all that well yet.
