This experiment has also a particular significance because it tests in quite an unusual way the predictions of quantum statistics as applied to BEC : it represents an unsuccessful attempt of falsification of the theory [ 1 ].
22.
One of his seminal achievements is the first experimental realisation of the " & nu; " = 5 / 2 fractional quantum Hall state : this is the only known quantum hall state labelled by an even denominator quantum number and it is believed in the condensed matter physics community that this state shows exotic non-abelian quantum statistics and other topological features.
