 s given by the symmetric group of particle permutations and indistinguisha
 ble particles behave like bosons or fermions. In contrast\, anyons have ge
 neralized exchange statistics determined by a different group that arises 
 from the topology of few-body configuration space. Specifically\, when the
  few-body configuration space is not simply-connected\, then generalized e
 xchange statistics can arise. Fractional exchange statistics given by the 
 braid group are the most famous kind of anyon\, but there are others that 
 could be implemented with cold atoms in optical traps and engineered inter
 actions. This talk will describe how the shape of the trap\, the defects c
 aused by particle interactions\, and indistinguishability can induce non-t
 rivial connectivity in configuration space and lead to  different families
  of anyons with different generalized exchange statistics and physical pro
 perties.
