On Aug. 12 Beijing time, Professor Zhang Yuanbo's group in Fudan University's physics department and collaborators published "Superconducting 2D cuprate with a single CuO2 plane" in Nature, reporting they thinned a cuprate high-temperature superconductor to a single CuO2 superconducting plane. The work confirms a two-dimensional origin for high-Tc superconductivity and reports an anomalous metallic state and quantum criticality at the superconductor–insulator transition, establishing a new quantum experimental platform to probe high-Tc mechanisms.
