DESCRIPTION:In recent years\, there have been considerable experimental ad
 vances in creating synthetic gauge fields and spin orbit coupling using op
 tical dressing techniques in systems of ultracold atoms.  Such advances pa
 ve the way to the realisation of quantum Hall and topologically insulating
  states in ultracold gases as well as states which have no counterpart in 
 the solid state. A hallmark feature of such topological states is the exis
 tence of edge modes.  However\, as bosons tend to condense\, the these edg
 e modes are typically irrelevant for near-equilibrium behaviour.  I will d
 iscuss a protocol to coherently populate the edge states through a dynamic
 al instability.  Time permitting\, in the remainder of the talk I will pre
 sent results on the quantum dynamics of spinor condensates in tight traps
