## Description

- description: Fractional quantum Hall (FQH) states are exotic quantum many-body phases
    whose elementary charged excitations are neither bosons nor fermions but anyons,
    obeying fractional braiding statistics. While most FQH states are believed to
    have Abelian anyons, the Moore-Read type states with even denominators, appearing
    at half filling of a Landau level (LL), are predicted to possess non-Abelian excitations
    with appealing potentials in topological quantum computation. These states, however,
    depend sensitively on the orbital contents of the single-particle LL wavefunctions
    and the mixing between different LLs. Although they have been observed in a few
    materials, their non-Abelian statistics still awaits experimental confirmation.
    Here we show magnetotransport measurements on Bernal-stacked trilayer graphene
    (TLG), whose unique multiband structure facilitates the interlaced LL mixing,
    which can be controlled by external magnetic and displacement fields. We observe
    a series of robust FQH states including even-denominator ones at filling factors
    ν = −9/2, −3/2, 3/2 and 9/2. In addition, we are able to finetune the LL mixing
    and crossings to drive quantum phase transitions of these half-filling states
    and their neighboring odd-denominator ones, exhibiting a related emerging and
    waning behavior. Our results establish TLG as a controllable system for tuning
    LL orbital contents and their mixing strengths, and a fresh platform to seek for
    non-Abelian quasi-particles.
