Observation of small Fermi pockets protected by clean CuO 2 sheets of a high- T c superconductor

Superconductivity in copper oxide materials emerges by doping a special kind of correlated state called the Mott insulator. However, studying what happens when a small concentration of charge carriers—holes or electrons—is added to a Mott insulator is experimentally challenging. It has been predicte...
