## Description

- description: "This letter presents our findings on the recursive band gap engineering
    of chiral fermions in bilayer\r\ngraphene doubly aligned with hBN. By utilizing
    two interfering moiré potentials, we generate a supermoiré pattern which renormalizes
    the electronic bands of the pristine bilayer graphene, resulting in higher-order
    fractal gaps even at very low energies. These Bragg gaps can be mapped using a
    unique linear combination of periodic areas within the system. To validate our
    findings, we used electronic transport measurements to identify the position of
    these gaps as functions of the carrier density and establish their agreement with
    the predicted carrier densities and corresponding quantum numbers obtained using
    the continuum model. Our study provides conclusive evidence of quantization of
    the momentum-space area of quasi-Brillouin zones in a minimally incommensurate
    lattice. It fills essential gaps in understanding the band structure engineering
    of Dirac fermions by a doubly periodic superlattice spinor potential."
