  • Spontaneous symmetry breaking of flat bands in twisted graphene systems may lead to anomalous Hall effect with a precursor state which has not been observed. Here, the authors probe this precursor state by observing bulk valley current and large nonlocal voltage several micrometers away from the charge current path in twisted double bilayer graphene.

  • Report of the likely observation of a Mott insulator in trilayer graphene with a moiré potential. The Mott state can be tuned between different filling fractions via gating, which will enable the careful study of this paradigmatic many-body state.

  • For appropriately aligned layers of different two-dimensional materials, the separation between layers—and hence the interlayer coupling—is very sensitive to pressure, leading to pressure-induced changes in the electronic properties of the heterostructures.
