At the National University of Singapore, researchers have discovered that a single-degree twist between two sheets of graphene creates a material so finely balanced between order and chaos that the faintest whisper of far-infrared light is enough to flip it from insulator to conductor. This quantum phase transition — electrons reorganizing without a single atom moving — mirrors the knife-edge sensitivity that made superconductors the world's most precise detectors, and now offers a new path into a region of the electromagnetic spectrum that has long resisted both electronics and optics.
