Resistance hysteresis in twisted bilayer graphene: Intrinsic versus extrinsic effects
Ranit Dutta, Ayan Ghosh, Kenji Watanabe +2
Hysteresis in resistance under magnetic field sweeps is a key signature for identifying magnetism in twisted bilayer graphene and similar systems. However, such sweeps can induce e…

Thermopower probing emergent local moments in magic-angle twisted bilayer graphene
Ayan Ghosh, Souvik Chakraborty, Ranit Dutta +7
Recent experiments on magic-angle twisted bilayer graphene (MATBLG) have revealed the formation of flatbands, suggesting that correlation effects are likely to dominate in this sys…

Electric field tunable superconductivity with competing orders in twisted bilayer graphene near magic-angle
Ranit Dutta, Ayan Ghosh, Shinjan Mandal +6
Superconductivity (SC) in twisted bilayer graphene (tBLG) has been explored by varying carrier concentrations, twist angles, and screening strength, with the aim of uncovering its…
