## Description

- description: 'We report transport measurements of fractional quantum Hall (FQH)
    states in the N=2 LL in bilayer graphene, a system with spin and valley degrees
    of freedom in all LLs, and an additional orbital degeneracy in the 8-fold degenerate
    N=0/N=1 LLs. In contrast with recent observations of particle-hole asymmetry in
    the N=0/N=1 LLs of bilayer graphene, the FQH states we observe in the N=2 LL are
    consistent with the composite fermion model: within a LL, they form a complete
    sequence of particle-hole symmetric states whose relative strength is dependent
    on their denominators. The FQH states in the N=2 LL display energy gaps of a few
    Kelvin, comparable to and in some cases larger than those of fractional states
    in the N=0/N=1 LLs.'
