## Description

- description: In multilayer moiré heterostructures, the interference of multiple
    twist angles ubiquitously leads to tunable ultralong-wavelength patterns known
    as supermoiré lattices. However, their impact on the system’s many-body electronic
    phase diagram remains largely unexplored. We present local compressibility measurements
    revealing numerous incompressible states resulting from supermoiré lattice–scale
    isospin symmetry breaking driven by strong interactions. By using the supermoiré
    lattice occupancy as a probe of isospin symmetry, we observed an unexpected doubling
    of the miniband filling near ν, possibly indicating a hidden phase transition
    or normal-state pairing proximal to the superconducting phase. Our work establishes
    supermoiré lattices as a tunable parameter for designing quantum phases and as
    an effective tool for unraveling correlated phenomena in moiré materials.
