Just a year ago, scientists presented results that seemed almost too good to be true: Carbon sheets only a single atom thick, called graphene, took on a pair of important physical properties when they were twisted at just the right “magic” angle relative to one another. If the atmosphere this month at the world’s largest physics conference was any indication, twisted graphene has now spawned an entirely new field of physics research.
