## Description

- description: Strong interactions between electrons in two-dimensional systems in
    the presence of a high magnetic field give rise to fractional quantum Hall states
    that host quasiparticles with a fractional charge and fractional exchange statistics.
    Here we demonstrate high-resolution scanning tunnelling microscopy and spectroscopy
    of fractional quantum Hall states in ultra-clean Bernal-stacked bilayer graphene
    devices. Spectroscopy measurements show sharp excitations that have been predicted
    to emerge when electrons fractionalize into bound states of quasiparticles. We
    found energy gaps for candidate non-abelian fractional states that are larger
    by a factor of five than those in other related systems, for example, semiconductor
    heterostructures, and this suggests that bilayer graphene is an ideal platform
    for manipulating these quasiparticles and for creating topological quantum bits.
    We also found previously unobserved fractional states in our very clean graphene
    samples.
