## Description

- description: Excitons, Coulomb-driven bound states of electrons and holes, are typically
    composed of integer charges. However, in bilayer systems influenced by charge
    fractionalization, a more interesting form of interlayer exciton can emerge, in
    which pairing occurs between constituents that carry fractional charges. Despite
    numerous theoretical predictions for these fractional excitons, their experimental
    observation has remained unexplored. Here we report transport signatures of excitonic
    pairing in fractional quantum Hall effect states. By probing the composition of
    these excitons and their impact on the underlying wavefunction, we discover two
    new types of quantum phases of matter. One of these can be viewed as the fractional
    counterpart of the exciton condensate at a total filling of 1, whereas the other
    involves a more unusual type of exciton that obeys non-bosonic quantum statistics,
    challenging the standard model of bosonic excitons.
