## Description

- description: "We present a comprehensive study of magnetotransport in high-mobility
    trilayer graphene (TLG) devices under a transverse displacement field, focusing
    on symmetry-broken Landau levels (LLs) from monolayer-like and bilayer-like bands.
    A striking displacement-field-induced enhancement of the Landé \U0001D454-factor
    is observed in the zeroth Landau level of the monolayer-like band, highlighting
    the formation of interaction-driven quantum Hall states. Additionally, we find
    a rich landscape of LL crossings in the Dirac gully region, accompanied by phase
    transitions between spin-, gully, and valley-polarized LLs. These experimental
    observations are successfully modeled using calculations based on optimized tight-binding
    parameters. Furthermore, our results reveal significant particle-hole asymmetry
    in the sequence of LLs in the Dirac gullies, attributed to differing \U0001D454-factor
    values for electrons and holes. This asymmetry underscores the limitations of
    noninteracting models in capturing the complexities of multiband systems. This
    work provides insights into the interplay of symmetry-breaking mechanisms and
    enhanced interaction effects in Bernal-stacked trilayer graphene, advancing our
    understanding of quantum transport phenomena in multiband systems."
