Abstract
In this talk, I will present a detailed experimental study of the particle- hole (PH) symmetry of the the abelian and a putative non-abelian Fractional Quantum Hall (FQH) state about half filling in a multiband system. Specifically, we focus on the lowest Landau level of the monolayer-like band of Bernal stacked trilayer graphene (TLG). In pristine TLG, the excitation energy gaps, Lande g factor, effective mass, and disorder broadening of the FQH states is the same as their hole-
conjugate counterpart. This precise PH symmetry stems from the lattice mirror symmetry that precludes Landau-level mixing. Introducing a non- zero displacement field D disrupts this mirror symmetry, facilitating the interaction and hybridization between the NM = 0 of monolayer-like and NB = 2 bilayer-like Landau levels. This band hybridization eventually leads to a violation of the particle-hole symmetry of the FQH states. We find the one-third and two-fifth FQH states to be more robust against Landau level m...
