Ev. Gorbar et Sv. Mashkevich, STATISTICAL SCREENING IN A P-INVARIANT, T-INVARIANT MODEL, Zeitschrift fur Physik. C, Particles and fields, 65(4), 1995, pp. 705-707
It is shown that in the P, T-invariant model with the mixed Chern-Simo
ns term the interaction of charge carriers leads to effective changing
of their statistics, which depends on distance between them. In parti
cular, in the limit of large distances fermions effectively turn into
bosons.
