Magic-angle graphene is an incredible multi-functional material, easily tuned amongst a diverse set of quantum phases by changing its temperature, magnetic field, and electronic density. Here, researchers have uncovered essential signatures of its unconventional superconducting phase (yellow), which conducts electricity with zero resistance and zero energy loss, and its previously unknown pseudogap regime (blue), a seemingly necessary precursor to superconductivity.
