Link between thermodynamic correlation signatures and superconductivity in twisted trilayer graphene (opens in new tab)

Twisted graphene multilayers exhibit strong electronic correlations leading to a range of experimental signatures. Yet how these signatures relate to each other and to the microscopic ground states—and how twist angle and band structure reshape them—remains poorly understood. Here we study this interplay by correlating local thermodynamic and transport measurements in twisted trilayer graphene with unequal angles and flat electronic bands. We use a scanning single-electron transistor to map t...
