Dielectric catastrophe at the Wigner-Mott transition in a moiré superlattice

The Wigner-Mott insulator is driven by extended Coulomb repulsion, rather than the on-site Coulomb repulsion of the Mott insulator. Here, the authors observe a continuous bandwidth-tuned transition between a metal and a Wigner-Mott insulator in a MoSe2/WS2 moiré superlattice at fractional lattice fi...
