V. Gurarie et E. Rezayi, Parafermion statistics and quasihole excitations for the generalizations of the paired quantum Hall states, PHYS REV B, 61(8), 2000, pp. 5473-5482
We continue the program started by N. Read and one of us: and explain the s
tatistics of the excitations for the generalizations of the paired states i
n the quantum Hall effect in terms of the parafermion statistics.: We show
that these excitations behave as combinations of bosons and parafermions. T
hat generalizes the prior treatment of the paired (Moore-Read) state where
the excitations behave as combinations of bosons and fermions. We explain w
hat it means, from a quantum-mechanical point of view, for a particle to be
a "parafermion" rather than a boson or a fermion and work through several
explicit examples. The resulting multiplets coincide exactly with the angul
ar momentum multiplets found numerically for the k+1-particle interaction H
amiltonian on a sphere. We present proof that the wave functions found prev
iously are indeed the correlation functions of the parafermion conformal fi
eld theory. We also obtain the tunneling characteristics into the parafermi
on edge, which can be used to distinguish the parafermion states from other
known states at the same filling.
