## Description

- description: We present a detailed experimental study of the effect of Landau level
    mixing on various FQHs about half filling in a multiband system, namely Bernal
    stacked trilayer graphene. In pristine TLG, the excitation energy gaps, Landé
    g-factor, effective mass, and disorder broadening of the odd-denominator FQH states
    are identical to their hole-conjugate counterpart. This precise PH symmetry stems
    from the lattice mirror symmetry that precludes Landau-level mixing. Introducing
    a non-zero displacement field D disrupts this mirror symmetry, facilitating the
    hybridization between the monolayer-like and bilayer-like Landau levels. This
    inter-band coupling enhances the Landau level mixing factor η and activates three-body
    interactions – both of which explicitly break the PHS of FQHs. As a result, various
    conventional FQHs are completely destabilized, offering a route to explore such
    mixing effects on FQHs in a controlled way. We establish that the PHS breaking
    in TLG is of extrinsic origin and is fundamentally distinct from the intrinsic,
    interaction-driven symmetry breaking observed in the lowest Landau levels of single-layer
    and bilayer graphene.
