Metal-Insulator Quantum Criticality in TMD Moire Bilayers
Prof. Vladimir Dobrosavljevic

Moiré bilayer materials have recently attracted much attention following the discovery of various correlated insulating states at specific band fillings. Here we discuss the metal-insulator transitions (MITs) that have been observed in the same devices, both at commensurate fillings where characteristic Mott and Wigner-Mott physics has been observed, but also at fillings far from these strongly correlated regimes, displaying many similarities to other examples of disorder-dominated MITs. We propose a minimal theoretical model describing the interplay of interactions and disorder, which is able to capture most experimental trends observed in these materials.
