Self-consistent renormalization of Chern-Simons term and correlations in system of anyons
Kogan Ya. I. , Khveshchenko D. V.
In the self-consistent approximation, the effect of the medium reduces to one of reducing the Chern-Simons coefficient by a factor of two, rather than erasing it altogether. Various properties of an anyon liquid, in particular, two-stage transmutation of the statistics, are discussed.
