The study investigates the tuning of superconductivity and correlated insulating phases in twisted bilayer graphene (tBLG) by varying the interlayer coupling and twist angle. The authors demonstrate that superconductivity can be induced at twist angles greater than 1.1° by applying hydrostatic pressure to reduce the interlayer spacing, which otherwise lacks these phases. They observe new correlated phases, including superconductivity near half-filling of the electron-doped band and resistive states at quarter-filling of both bands in devices with a twist angle of 1.14°. Varying the layer imbalance reveals competition between superconductivity and correlated insulating phases, likely due to differences in disorder. At a twist angle of 1.27°, superconductivity is observed at high pressure, with a critical temperature (Tc) of about 3 K, significantly higher than previously reported. High-resolution magnetoresistance oscillations provide insights into the structure of the flat electronic band and its relationship to the correlated states. The study also explores the influence of disorder, quantum oscillations, and isospin ordering, suggesting that the nature of the Fermi surface nucleated at half-filling is crucial for the onset of superconductivity.The study investigates the tuning of superconductivity and correlated insulating phases in twisted bilayer graphene (tBLG) by varying the interlayer coupling and twist angle.
