Observation of anyons in fractional quantum Hall systems

While the occurrence of anyon-excitations in the fractional quantum Hall effect is a robust theoretical prediction (see the references above), and while the fractional quantum Hall effect itself has long been established in experiment, the actual observation of anyons in these systems is subtle:

An early claim of the observation of non-abelian anyons seems to remain unconfirmed:

• Sanghun An, P. Jiang, H. Choi, W. Kang, S. H. Simon, L. N. Pfeiffer, K. W. West, K. W. Baldwin, Braiding of Abelian and Non-Abelian Anyons in the Fractional Quantum Hall Effect [arXiv:1112.3400]

The claimed observation of abelian anyons is more securely established:
