Physicists were stunned when two twisted sheets of graphene showed signs of superconductivity. Now Stanford scientists have shown that the wonder material also generates a type of magnetism once only dreamed of theoretically.
Theoretical physicist Shamit Kachru and three of his graduate students talk about the social fabric behind their research, the cycle of confusion and discovery, and the sense of awe – or the cool factor – that drives them.
With some Stanford-led upgrades, the gravitational wave detector LIGO is back online after a year of work. It’s now more sensitive than ever to spacetime ripples and will be joined by other detectors around the world.
