Even Denominator Fractional Quantum Hall States in the Zeroth Landau Level of ABA Trilayer Graphene

Author(s): Tanima Chanda, Simrandeep Kaur, Harsimran Singh, Kenji Watanabe, Takashi Taniguchi, Manish Jain, Udit Khanna, Ajit C. Balram, and Aveek Bid Even-denominator fractional quantum Hall states at half-filling are of particular interest because they can host non-Abelian quasiparticles. Here, we report the emergence of such states in the zeroth Landau level ($N=0$) of ABA trilayer graphene (TLG), challenging the conventional expectation that t… [Phys. Rev.
