DESCRIPTION:New forms of quantum statistics on graphs\nJon Harrison\, Baylo
 r University\nWe consider the quantum statistics of indistinguishable part
 icles on a graph. In three dimensions quantum states are symmetric or anti
 -symmetric under exchange of pairs of identical particles\, corresponding 
 to Bose-Einstein or Fermi-Dirac statistics respectively. Restricting the p
 articles totwo dimensions topologically inequivalent exchange paths corres
 pond to elements of the braid group instead of the symmetric group. This o
 pens up the possibility of Anyon statistics on a surface\, characterized b
 y a single free choice of an exchange phase. We consider the case when the
  particles are further restricted to lie on a quasi-one-dimensional networ
 k\; a graph. For sufficiently complex graphs new forms of statistics emerg
 e. Quantum statistics of indistinguishable particles on graphs may be char
 acterized by multiple independent free Anyon phases and discrete-valued ph
 ases. Possible applications of the new forms of quantum statistics include
  topological quantum computing\, the fractional quantum Hall effect\, supe
 rconductivity\, topological insulators and molecular physics. This is work
  with JP Keating and JM Robbins at Bristol University. Proc. R. Soc. A doi
