Misaligned stacks of the wonder material exhibit superconductivity and other curious properties.

Physicists are optimistic that the crossover between two previously separate fields — 2D materials and strongly correlated systems — will lead to exciting results. “It’s giving us an opportunity to talk to a whole community of people we haven’t had the chance to talk to in the past,” says Dean. And applied physicists are thinking about how the unusual properties of twisted 2D stacks might be harnessed to store and process information in super-efficient ways. Rotating or squeezing materials could also become a new way to switch an electronic device’s behaviour.



Authors Bio:
Born in Long Island public school year in Sweden as exchange student, went to Harvard one year, Cooper Union in NYC as Art student. Have two children, one of whom is rock mogul, the other has three daughters, one of whom has two daughters, making me a great grandmother at 68, very proud. For twenty years I operated a private primary school, Orchard School, in Santa Cruz CA. Still going strong but I'm retired and write much of the time. Strong believer in the space program and our subconscious quest as a species to prevent celestial onslaughts of one kind and another, for which it is my conviction that we have developed nuclear power, though we've had to use false wars to do so; in the end I believe we'll redeem ourselves in this way, which is why I find the abandonment of the shuttle program so sad. The Russians will do the honors with the next menace from Heaven, or have said that they will. In any case, nothing matters much if we don't, not the debt ceiling, pollution, nothing. All moot.
