Query: Anyon exciton revisited: Exact solutions for a few-particle system   The anyon exciton model is generalized to the case of a neutral exciton
consisting of a valence hole and an arbitrary number N of fractionally-charged
quasielectrons (anyons). A complete set of exciton basis functions is obtained
and these functions are classified using a result from the theory of
partitions. Expressions are derived for the inter-particle interaction matrix
elements of a six-particle system (N=5), which describes an exciton against the
background of an incompressible quantum liquid with filling factor 2/5. Several
exact results are obtained in a boson approximation, including the binding
energy of a (N+1)-particle exciton with zero in-plane momentum and zero
internal angular momentum.
