## Description

- description: Moiré materials host a wealth of intertwined correlated and topological
    states of matter, all arising from flat electronic bands with nontrivial quantum
    geometry. A prominent example is the family of alternating-twist magic-angle graphene
    stacks, which exhibit symmetry-broken states at rational fillings of the moiré
    band and superconductivity close to half filling. Here, we introduce a second
    family of twisted graphene multilayers made up of twisted sheets of M- and N-layer
    Bernal-stacked graphene flakes. Calculations indicate that applying an electric
    displacement field isolates a flat and topological moiré conduction band that
    is primarily localized to a single graphene sheet below the moiré interface. Phenomenologically,
    the result is a striking similarity in the hierarchies of symmetry-broken phases
    across this family of twisted graphene multilayers. Our results show that this
    family of structures offers promising new opportunities for the discovery of exotic
    new correlated and topological phenomena, enabled by using the layer number to
    fine tune the flat moiré band and its screening environment.
