  bibo_abstract:
  - "Owing to their wide tunability, multiple internal degrees of freedom, and low
    disorder, graphene heterostructures are emerging as a promising experimental platform
    for fractional quantum Hall (FQH) studies. Here, we report FQH thermal activation
    gap measurements in dual graphite-gated monolayer graphene devices fabricated
    in an edgeless Corbino geometry. In devices with substrate-induced sublattice
    splitting, we find a tunable crossover between single- and multicomponent FQH
    states in the zero energy Landau level. Activation gaps in the single-component
    regime show excellent agreement with numerical calculations using a single broadening
    parameter \r\nΓ≈7.2K. In the first excited Landau level, in contrast, FQH gaps
    are strongly influenced by Landau level mixing, and we observe an unexpected valley-ordered
    state at integer filling ν=−4.@eng"
