DESCRIPTION:The fractional quantum Hall states\, which occur in certain tw
o-dimensional electron systems in a strong magnetic field\, are strongly c
orrelated electron states that exhibit a number of very remarkable propert
ies. It can be shown mathematically that these systems host quasiparticle
with fractional charge and either fractional statistics or its extension\
, non-Abelian statistics. However\, experiments to directly demonstrate th
ese properties have proved challenging to carry out. My talk will review t
he definitions of these concepts\, as they apply to quantum Hall systems\,
and will review some recent experimental developments related to them\, i
ncluding the recent observations of fractional statistics in the state at
Landau level filling fraction 1/3. [1\,2\,3]\n\nReferences:\n\n[1] J. Nak
