The stunning emergence of a new type of superconductivity with the mere twist of a carbon sheet has left physicists giddy, and its discoverer nearly overwhelmed.
From my April 30, 2019, article in Quanta Magazine (also published in Wired)
Pablo Jarillo-Herrero is channeling some of his copious energy into a morning run, dodging startled pedestrians as he zips along, gradually disappearing into the distance. He’d doubtlessly be moving even faster if he weren’t dressed in a sports coat, slacks and dress shoes, and confined to one of the many weirdly long corridors that crisscross the campus of the Massachusetts Institute of Technology.
Jarillo-Herrero has never been a slacker, but his activity has jumped several levels since his dramatic announcement in March 2018 that his lab at MIT had found superconductivity in twisted bilayer graphene — a one-atom-thick sheet of carbon crystal dropped on another one, and then rotated to leave the two layers slightly askew….Read more
