Query: Charge and spin fractionalization in strongly correlated topological
  insulators   We construct an effective topological Landau-Ginzburg theory that describes
general SU(2) incompressible quantum liquids of strongly correlated particles
in two spatial dimensions. This theory characterizes the fractionalization of
quasiparticle quantum numbers and statistics in relation to the topological
ground-state symmetries, and generalizes the Chern-Simons, BF and hierarchical
effective gauge theories to an arbitrary representation of the SU(2) symmetry
group. Our main focus are fractional topological insulators with time-reversal
symmetry, which are treated as generalizations of the SU(2) quantum Hall
effect.
