Quantum criticality in twisted transition metal dichalcogenides

Near the boundary between ordered and disordered quantum phases, several experiments have demonstrated metallic behaviour that defies Landau Fermi paradigm1–5. In moiré heterostructures, gate-tuneable insulating phases driven by electronic correlations been recently discovered6–23. Here, we use transport measurements to characterize metal–insulator transitions (MITs) in twisted WSe2 near half filling of first subband. We find MIT as a function both density displacement field is continuous. At boundary, resistivity displays strange metal at low temperatures, with dissipation comparable Planckian limit. Further into phase, liquid recovered temperature, this evolves critical fan intermediate before eventually reaching an anomalous saturated regime room temperature. An analysis residual indicates presence strong fluctuations phase. These results establish new platform study doping bandwidth-controlled phase on triangular lattice. Metal-to-insulator are characterized WSe, revealing criticality temperatures.
